Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 249 Issued at 2200Z on 05 Sep 2012
IA. Analysis of Solar Active Regions and Activity from 04/2100Z
to 05/2100Z: Solar activity was low. Region 1564 (S14E01 -
Esi/beta-gamma) produced occasional C-class flares including a C6 at
05/0347Z and a C7/Sn at 05/0806Z, neither of which were associated
with significant radio emission. Region 1564 showed gradual spot and
penumbral decay during the period, but retained a beta-gamma
configuration due to polarity mixing in the vicinity of its
intermediate spots. Region 1560 (N04W58 - Eai/beta-gamma-delta)
showed minor spot loss in its trailer portion during the period. It
retained a delta within its intermediate spots, but the delta
appeared to be dissipating. The remaining spotted region were
unremarkable. No new regions were numbered. No Earth-directed CME
activity occurred during the period.
IB. Solar Activity Forecast: Solar activity is expected to be low
through the period (06 - 08 September) with a chance for an isolated
M-class flare during days 1 - 2.
IIA. Geophysical Activity Summary 04/2100Z to 05/2100Z:
Geomagnetic field activity ranged from quiet to major storm levels
with a brief period of severe storm levels at high latitudes. An
interplanetary shock passed the ACE spacecraft at 04/2203Z
indicating the arrival of the CMEs observed on 02 September. Field
activity increased to major storm levels during 05/0000 - 0300Z
following the shock, then decreased to minor storm levels during
05/0300 - 0600Z. A further decrease to active levels occurred during
05/0300 - 0900Z. Quiet to unsettled levels occurred during the rest
of the period with active to minor storm levels detected at high
latitudes.
IIB. Geophysical Activity Forecast: Geomagnetic field activity is
expected to be at quiet to unsettled levels through the period (06 -
08 September) with a chance for active levels on day 1 due to
possible weak coronal hole high-speed stream effects.

Joint USAF/NOAA Report of Solar and Geophysical Activity SDF Number 191 Issued at 2200Z on 09 Jul 2012 IA. Analysis of Solar Active Regions and Activity from 08/2100Z to 09/2100Z: Solar activity was low. Region 1515 (S15W89) produced the largest event of the period, a C7/Sf at 09/0830Z. Region 1520 (S17E33) continued its growth phase in area coverage, spot count and magnetic complexity, but remained relatively quiet through the period. New Region 1521 (S22E21) was numbered as a D-type group. A large filament eruption was observed in the SW quadrant at about 09/0930Z. At the time of its eruption, the 23 degree long filament was centered near S35W32. No Earth-directed CMEs were observed during the previous 24 hours. IB. Solar Activity Forecast: Solar activity is expected to be moderate with a chance for X-class events for the next three days (10 - 12 July). IIA. Geophysical Activity Summary 08/2100Z to 09/2100Z: The geomagnetic field was at unsettled to minor storm levels with high latitude major storm intervals. This activity was most likely a result of CME effects from the 04 July M1 event. ACE solar data indicated wind velocities ranged between 400 to 450 km/s. The Bz component of the interplanetary magnetic field was generally south throughout the period ranging between -5 to -10 nT from about 09/0600Z through the end of the period. Interplanetary field strength was at 10 to 12 nT through most of the period. A greater than 10 MeV proton event at geosynchronous orbit began at 09/0130Z, reached a maximum of 19 pfu at 09/0430Z and ended at 09/1445Z. This weak SEP event was most likely associated with the 08 July M6/1n flare from Region 1515. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at mostly quiet to unsettled levels with isolated active periods on day one (10 July) due to possible weak effects from the 06 July CME. A return to mostly quiet conditions is expected for days two and three (11 - 12 July). III. Event Probabilities 10 Jul-12 Jul Class M 80/80/80 Class X 25/25/25 Proton 10/10/10 PCAF yellow IV.

latest current solar flare storm activity july 6 2012
Sunspot 1515 has been teasing us with countless M-Class solar flares and it finally did what it has been threatening to do over the past several days. A major X1.1 Solar Flare was detected at 23:08 UTC. This event triggered a 10cm Radio Burst and a Type IV Sweep Frequency Event. The blast did generate a Coronal Mass Ejection, but it looks to be headed south and to the west. This should have little impact on Earth. The protons blasted away from the flare site are currently streaming past Earth and a S1 Minor Radiation Storm is in progress.
Begin Time: 2012 Jul 06 2322 UTC
Description: Type IV emissions occur in association with major eruptions on the sun and are typically associated with strong coronal mass ejections and solar radiation storms.
Begin Time: 2012 Jul 06 2304 UTC
Maximum Time: 2012 Jul 06 2306 UTC
End Time: 2012 Jul 06 2306 UTC
Duration: 2 minutes
Peak Flux: 520 sfu
Description: A 10cm radio burst indicates that the electromagnetic burst associated with a solar flare at the 10cm wavelength was double or greater than the initial 10cm radio background. This can be indicative of significant radio noise in association with a solar flare. This noise is generally short-lived but can cause interference for sensitive receivers including radar, GPS, and satellite communications.
Aurora Watch
Currently our Geomagnetic Field is fairly quiet and visible aurora would be possible only around the polar regions. An increase in geomagnetic activity will be possible starting tomorrow should a CME sweep past our planet as predicted. A potential for minor geomagnetic storming watch was issued today by the NOAA Space Weather Prediction Center.
NOAA Scale: Periods reaching the G1 (Minor) Level Likely
Valid for UTC Day: 2012 Jul 07
Solar Update / Large Sunspots
Solar activity is currently strong with an X1.1 Solar Flare detected around Sunspot 1515. A Coronal Mass Ejection was produced, but does not look to be Earth direcfted. While Sunspot 1515 currently has all the attention, we should also continue to monitor the large new sunspot that rotated into view off the southeast limb. This region did produce an M1.3 Solar Flare at 18:55 UTC Friday.

SDF Number 188 Issued at 2200Z on 06 Jul 2012
IA. Analysis of Solar Active Regions and Activity from 05/2100Z
to 06/2100Z: Solar activity was moderate. Region 1515 (S18W50)
continued to produce M-class flares, the largest an M2/Sn at
06/0140Z. The region continued to grow to 900 millionths and
maintained a beta-gamma-delta magnetic configuration. Region 1513
(N15W65) showed slight decay and is now considered an Hsx-alpha type
spot group.
IB. Solar Activity Forecast: Solar activity is expected to be
moderate with a chance for X-class flares for the next three days
(07-09 July).
IIA. Geophysical Activity Summary 05/2100Z to 06/2100Z:
The geomagnetic field was quiet to unsettled during the past 24
hours. The greater than 2 MeV electron flux at geosynchronous orbit
reached high levels during the period.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be unsettled to active with a chance for minor storm
conditions on days one and two (07-08 July) due to combined effects
from the CMEs observed on 03 and 04 July. Quiet to unsettled
conditions are expected on day three (09 July) as effects from the

Report of Latest Solar Wind Storm Activity May 5 2012
Solar activity increased to moderate levels thanks to newly numbered Sunspot 1476. This new region rotated into view off the northeast limb and has so far produced a pair of M-Class flares. The latest event was an M1.3 at 23:01 UTC Saturday evening. solar activity is again increasing.
Solar activity increased somewhat due to the new sunspot rotating into view off the northeast limb. This region should be numbered 1476 on Saturday. There will be a chance for an M-Class event. All other regions have been fairly quiet with the exception of a C2.0 flare around Sunspot 1471 in the southern hemisphere.
Updated May 05 2200 UTC
Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 126 Issued at 2200Z on 05 May 2012
IA. Analysis of Solar Active Regions and Activity from 04/2100Z
to 05/2100Z: Solar activity was at moderate levels. New Region 1476
(N09E67) produced several C-class flares along with an M1/Sn at
05/1329Z. The regions proximity to the limb makes spot
classification difficult, however, it is currently considered a
Dko-beta type group. Region 1469 (S26W77) continues to produce low
level C-class activity as it rotates around the west limb. A model
run was completed after the forecast was issued yesterday to include
the CME observed off the southwest limb yesterday. It was determined
that the CME has a slight Earth-directed component. A second CME,
first visible in STEREO A COR2 imagery at 05/0309Z, appeared to be
associated with a C1 flare from Region 1469 observed at 04/2350Z.
Although both CMEs have a weak Earth-directed component, neither are
expected to cause significant geomagnetic activity. A third CME
associated with a C2/Sf flare from Region 1470 (S15W31) observed at
05/0639Z, first became visible in SDO AIA imagery at approximately
05/0600Z. Due to the source location, it is probable that the CME is
Earth-directed and a model run is currently in progress to determine
geoeffectiveness.
IB. Solar Activity Forecast: Solar activity is expected to be low
with a chance for M-class flares for the next three days (06-08
May).
IIA. Geophysical Activity Summary 04/2100Z to 05/2100Z:
The geomagnetic field was quiet during the past 24 hours.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be quiet on day one (06 May). Quiet to unsettled
conditions are possible on days two and three (07-08 May) due to
weak effects from the CMEs observed on 04 May.

IA. Analysis of Solar Active Regions and Activity from 02/2100Z
to 03/2100Z: Solar activity has been at low levels for the past 24
hours. Multiple C-class events were observed during the period with
the largest event being a C2/Sf x-ray flare from new Region 1475
(N05E61). Even though Region 1475 is magnetically classified as an
alpha group, it remains responsible for a majority of todays
activity. There are currently seven sunspot regions on the disk,
with many regions stable or in a waning phase. No Earth directed
CMEs were observed in the past 24 hours.
IB. Solar Activity Forecast: Solar activity is expected to be at
low levels with a slight chance for M-class events for the next
three days (04 - 06 May).
IIA. Geophysical Activity Summary 02/2100Z to 03/2100Z:

Latest Solar Flare Activity Update April 27 2012
Solar activity increased to moderate levels with an M1.0 solar flare detected Friday morning around Sunspot 1466 in the northern hemisphere. Sunspot 1465 in the south produced a minor C2.4 flare at 11:02 UTC. Sunspot 1469 located in the southeast quadrant, appears to be growing on Friday. Finally, A new region looks to be hiding on the southeast limb and will soon begin to rotate into view. There will continue to be a small chance for an isolated M-Class flare.
Sunspot Update: The region hiding on the southeast limb is now rotating into view and a Sunspot is
Joint USAF/NOAA Report of Solar and Geophysical Activity SDF Number 118 Issued at 2200Z on 27 Apr 2012 IA. Analysis of Solar Active Regions and Activity from 26/2100Z to 27/2100Z: Solar activity was at moderate levels due to an M1/1n flare at 27/0824Z from Region 1466 (N11W38). Other activity consisted of single, low-level C-class flares from Regions 1459 (S19W88), 1465 (S17W53), 1467 (N11E32), 1469 (S24E28) and 1466. During the period, Region 1465 developed into a beta-gamma-delta magnetic configuration while the remaining regions showed little change. Numerous non-Earth directed CMEs were observed off the SW limb over the past 24 hours, all originating from old Region 1462 (S25, L=139) which rotated around the west on 24 April. IB. Solar Activity Forecast: Solar activity is expected to be low with a slight chance for M-class activity for the next three days (28 - 30 April). IIA. Geophysical Activity Summary 26/2100Z to 27/2100Z: The geomagnetic field was at quiet to unsettled levels. Through the period, ACE solar wind velocities steadily decreased from about 560 km/s to near 500km/s while the Bz component of the interplanetary magnetic field was variable between +/-4 nT. The greater than 2 MeV electron flux at geosynchronous orbit was at high levels throughout the period. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at predominately quiet levels for the next three days (28 - 30 April).

Report of latest solar flare activity April 26 2012
IA. Analysis of Solar Active Regions and Activity from 25/2100Z
to 26/2100Z: Solar activity was at low levels. Region 1460 (N15W93)
and Region 1465 (S18W39) both produced C1 x-ray events at 25/2242Z
and 26/1723Z respectively. Both had associated CMEs but neither are
expected to be geoeffective. Three consecutive CMEs appeared on
LASCO/C2 imagery at 26/0924Z, 26/1148Z, and 26/1638Z. All three
were around the west limb and are not expected to be geoeffective.
IB. Solar Activity Forecast: Solar activity is expected to remain
low with a slight chance for M-class activity for the next three
days (27 - 29 April).
IIA. Geophysical Activity Summary 25/2100Z to 26/2100Z:
The geomagnetic field started the period at minor storm levels, but
fell to quiet levels and remained mostly quiet for the remainder of
the period. This activity was attributed to Coronal Hole High Speed
Stream (CH HSS) effects. Solar wind speeds have steadily decreased
from approximately 730 km/s to approximately 560 km/s. The Bz
component of the interplanetary magnetic field has remained fairly
neutral with minor fluctuations between +3 and -5 nT. Overall, the
total field fluctuated between +2 and +8 nT. The greater than 2 MeV
electron flux at geosynchronous orbit was at high levels throughout
the period.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be at quiet to unsettled levels with isolated active
periods for day one (27 April) as CH HSS effects begin to wane.
Days two and three (28 -29 April) are expected to be mostly quiet.
A long lasting Geomagnetic Storm that reached very close to the Strong G3 Level took place Monday night and early Tuesday morning. Visible Aurora was seen in many locations and Ham Radio operators were able to make numerous contacts via the Aurora on the 6 meter (50mhz) amateur radio band. This storm was due to a sharply south pointing component of the Interplanetary Magnetic Field (IMF) that allowed the solar wind to flow in and generate aurora. Things are now starting to return to quieter levels.
UPDATE: Minor Geomagnetic Storm conditions (Kp=5) did again flare up on both Tuesday and Wednesday evenings. The solar wind is currently near 500 km/s. Be on the lookout for Aurora at very high latitudes.
Updated 4/26/2012 @ 13:40 UTC
Solar Update
Solar activity is currently at very low levels. Sunspot 1460 just rotated onto the western limb and out of direct Earth view. Sunspot 1459 which continues to decay, will also join 1460 on the limb by the weekend. Elsewhere, Sunspot 1465 did have a Beta-Gamma-Delta magnetic configuration, but has itself decayed and is no longer a threat for strong solar flares. There will continue to be a chance for C-Class flares.

Solar Flare Impact in 2012
Solar Cycles
Just like how the earth has 4 seasons throughout the year, the sun goes through "solar cycles" taking 11 years to complete. The previous cycle was at its peak in 2001. Every cycle has a stage when the flares are most powerful, often occurring close to the solar equator, known as the "solar maximum", with the next massive one expected to take place in December 21, 2012 - a date predicted by the Mayan Calendar! Recently, the sun has been going through a long period of quiet solar activity as scientists have concluded that the sun is closing in on the final cycle. The quiet period alarmed NASA scientists and as they issued warnings that we will be seeing a seriously violent sun storm soon.
Impact to Earth
Many solar flares that hit earth were minor, however, small flares can still be threatening. For example, in 1989 a flare struck North America and wiped out many electric grids in the United States and Canada resulting in blackouts. Solar flares are also known to affect human life because a huge flare that's predicted to strike in 2012 would completely take out satellites, telecommunications, computers, and GPS.
Solar flares 2012 predictions are one of many cataclysmic events slated for the year of uncertainty. Always be informed on the latest news and learn ways to prepare and survive the 2012 predictions doomsday.

SDF Number 089 Issued at 2200Z on 29 Mar 2012
IA. Analysis of Solar Active Regions and Activity from 28/2100Z
to 29/2100Z: Solar activity has been at low levels. There were six
C-class flares over the past 24 hours with five of these originating
from old Region 1429 (N19, L=299) which is just beginning to rotate
into view as of forecast issue time. The largest flare was a C7
that occurred at 29/0953Z and originated from old Region 1429. New
Region 1449 (S18W17) was numbered today and is a D-class spot group.

Latest Report of Solar Flare
SDF Number 087 Issued at 2200Z on 27 Mar 2012
IA. Analysis of Solar Active Regions and Activity from 26/2100Z
to 27/2100Z: Solar activity has been at low levels. Region 1444
(N21W17) produced a C5/1f flare at 27/0308Z. Region 1442 (N12W13)
produced a C2 flare at 26/2338Z and a C1/Sf flare at 27/0430Z. SOHO
LASCO observed a full asymmetric halo CME at 26/2312Z which was
associated with Type II & Type IV radio sweeps. This CME was
determined to be a backsided event and should not be geoeffective.
IB. Solar Activity Forecast: Solar activity is expected to be low
with a chance for an isolated M-class flare. Old Region 1429 (N19,
L=299) is expected to return to the solar disk midday on 29 March,
which should increase M-class flare probabilities. New Region 1447
(S25W55) was numbered today and is a small C-type spot group.
IIA. Geophysical Activity Summary 26/2100Z to 27/2100Z:
The geomagnetic field was at quiet to unsettled levels. ACE data
indicate a solar sector boundary crossing during the period.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be at quiet to unsettled levels for 28 March to 29
March, due to a favorably positioned negative polarity coronal hole.
Quiet levels are expected on the third day (30 March).

IA. Analysis of Solar Active Regions and Activity from 25/2100Z
to 26/2100Z: Solar activity has been at low levels. Region 1442
(N12W01) produced a C1/Sf flare at 26/0642Z.
IB. Solar Activity Forecast: Solar activity is expected to be low
with a chance for an M-class flare. Old Region 1429 (N19, L=295) is
expected to return late on day 2 (28 March), further increasing the
possibility of an M-class event.
IIA. Geophysical Activity Summary 25/2100Z to 26/2100Z:
The geomagnetic field was at quiet levels.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be mostly quiet on 27 March, increasing to unsettled to
active conditions on 28 and 29 March due to a solar sector boundary
followed by a negative polarity coronal hole.
Solar activity has been fairly quiet with only low level C-Class flare detected. New Sunspot growth appears to be taking place on Monday in the vicinity of region 1442. This is located just to the south of AR1444. A couple of small plasma clouds are seen in the latest STEREO Behind COR2 images and may be the result of prominences lifting off of the Sun. None appear to be Earth directed at this time.

Solar and Geophysical Activity Report of 06 Mar 2012
Updated Mar 06 2200 UTC
Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 066 Issued at 2200Z on 06 Mar 2012
IA. Analysis of Solar Active Regions and Activity from 05/2100Z
to 06/2100Z: Solar activity was high. There were five M-class x-ray
events during the past 24 hours, all from Region 1429 (N17E31). The
largest event was an M2/1n 06/1241Z. None of these events was
associated with a CME that would be expected to be geoeffective.
Region 1429 dominates the disk in area (about 1010 millionths), and
exhibited growth during the period. The trailer portion showed the
most development but has separated a bit from the main cluster of
spots. The central portion is magnetically complex and shows
multiple deltas as well as strong shear along a pair of east-west
polarity inversion lines. Region 1428 (S17E08) also showed some
growth during the period (area of 280 millionths) but is simple
magnetically and was relatively quiet.
IB. Solar Activity Forecast: Solar activity is expected to be
moderate. Additional M-class events from Region 1429 are likely.
There is also a chance for a major flare and/or proton producing
event from Region 1429 during the next three days (07-09 March).
IIA. Geophysical Activity Summary 05/2100Z to 06/2100Z:
The geomagnetic field ranged from quiet to active levels with
isolated minor storm periods at high latitudes. ACE solar wind
measurements of the interplanetary magnetic field showed steady
strengthening during the period and there were numerous intervals of
weakly southward Bz. The greater than 10 MeV proton enhancement
continued throughout the period and reached a peak value of 4 PFU at
06/1335Z. The flux appeared to be on a slow declining trend at the
end of the period. The greater than 2 MeV electron flux at
geosynchronous orbit reached high levels during the period.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be unsettled to active with a chance for minor storm
periods during the next 24 hours (07 March). The increase in
activity is expected due to combined effects from a co-rotating
interaction region with the CME that occurred on 04 March
(associated with the M2 x-ray event). Later in the day additional
effects are expected due to a glancing blow from the full halo CME
associated with the X1 x-ray event that occurred on 05 March.
Predominantly unsettled levels with a chance for active periods are
expected for the second day (08 March) as effects from the
anticipated disturbance should diminish. Predominantly quiet levels
are expected for the third day (09 March).

The strongest solar storms outbreak in five years - Autos
NASA's solar dynamics observation satellite measurements to five years of the most violent
solar radiation outbreak, arrived in earth can cause moderate geomagnetic storms, influence on
earth satellite communication and power supplies. According to the observation of solar
dynamics observation satellite, aside from a small radiation storm outside, the sun eruption
coupled with a flare and a halo material eruption.
The national weather service space weather prediction center project coordinator Cardiff, bill
mourinho tower said: "this time the outbreak started very dramatic." He pointed out that
medium solar flare in 6 at 1am edt 41 points (the GMT at 5 a.m. 41 points) peak. "We first
observed flare scale doesn't big, in the ensuing eruption process, we observed high-energy
particle radiation and large-scale halo material eruption. Can you observed out from the sun
all the material, the surface is very spectacular sight."
The sun dynamics observation satellite launched in 2010, filming the sun outbreaks of high-
definition pictures and video. According to the observation, the sun eruption in visually
spectacular, because of the earth, not positive influence on the earth can be very small. NASA
said in a statement: "rising particle formation huge mushroom, then fell back to the sun to
the surface, seems covered nearly half of the sun to the surface."
Randolph points out, intentions space weather analysts are eyeing the sun eruption, to
determine whether it leads to the sun and earth happened between magnetic field collide. Sun
in about 150 million km distance to the left. He said in an interview with the French media:
"part of our job is to monitor the sun and determine whether an outbreak of substance is
flying to the earth, because the material basically is jet with gas and magnetic. In a day or
two, we will see time some of the substance in the sun injection effect, form the earth. We do
not believe that geomagnetic storms this will be a very severe geomagnetic storms, but
strength can still reach the medium level."
Space weather prediction center, said the sun eruption triggered in 8 small to medium-sized
geomagnetic storms, from about the GMT 18 PM. Any geomagnetic storms activities will end in 24
hours. The national weather service said: "the sun radiation during the storm there are lots
of high-energy protons, this type of activity since since December 2006 was the first
observed."
A total of 12 satellite and spacecraft to the moon, NASA surveillance sunlight layer survey of
the instrument to be able to carry the orbiter to radiation that can be measured and analyzed
the influence of. Radiation effects cosmic ray telescope (CRaTER) project chief researcher Hal
orchid spencer said: "CRaTER task two years ago, this is starting to see the most important
event. This is an exciting moment. Ironically, in planning this task, we originally thought
should be in the sun, because acuteness activity peaks launch the solar particles activities
usually in this period. In fact, we in the sun, and the sun tiny period launch activities will
take a long time to revive. This is an interesting and important moment, because all the signs
are that the sun was back to active state."
The sun from an outbreak of geomagnetic storms on earth will affect some of the grid, global
positioning systems use satellites and other equipment, but also will lead to fly over the
polar regions of the flights are over to change course. He said: "normally would not cause
greater destruction, threat within the scope of the controllable. If by jet to Asia, from the
United States over the arctic, you'll find ten flights. Every day is like this. When massive
radiation storm, some airlines will because of safety concerns to change course, away from the
flight to ensure flight polar regions keep communications smooth. The company will also
operating satellites close attention, because geomagnetic storms will in various ways to
interfere with satellite and received signal receiver." NASA says, in 8 evening and 9, polar
regions may also observed aurora borealis and aboard.

Latest Report of Solar Flare Activity Feb 2012
Updated Feb 20 2200 UTC
Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 051 Issued at 2200Z on 20 Feb 2012
IA. Analysis of Solar Active Regions and Activity from 19/2100Z
to 20/2100Z: Solar activity was low. There were three C-class flares
during the past 24 hours. The largest of these was a C4/Sf at 0509Z
from Region 1421 (N18E32). Region 1422 (N16W11) produced the other
two C-flares and is currently the largest group on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be low.
IIA. Geophysical Activity Summary 19/2100Z to 20/2100Z:
The geomagnetic field was unsettled to active with some isolated
storm periods at high latitudes. Solar wind data from ACE indicated
the influence of a high speed stream from a coronal hole. The
greater than 2 MeV electron flux at geosynchronous orbit reached
high levels during the period.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be unsettled with a chance for active periods on the
first day (21 Feb) due to continued effects from the high speed
stream. A decrease to mostly quiet levels is predicted for the
second day (22 Feb) and quiet levels are expected to continue for
the third day (23 Feb).
