M9.3 Eruption / Earth Directed CME / Radiation Storm

September 5, 2017 @ 19:00 UTC

Strong G3 Storm Watch

Possibly a treat in the works for aurora sky watchers. A Strong (G3) geomagnetic storm watch will be in effect beginning Wednesday (September 6) when the coronal mass ejection (CME) observed Monday is expected to sweep past Earth. Sky watchers across middle to high latitudes should be alert during the next 48 hours. More updates regarding this to follow.

M5.5 Eruption / Earth Directed CME / Radiation Storm

Moderately strong M5.5 solar flare event observed around region 2673 on Monday evening.UPDATE: An update regarding the M5.5 solar flare event around region 2673 this evening at 20:33 UTC. The flare was associated with a Type II radio emission with an estimated velocity of 1472 km/s, along with a 10cm radio burst (TenFlare) lasting 52 minutes and measuring 1600 solar flux units (SFU). Low energy proton levels as measured by the GOES-13 spacecraft are currently on the rise. Updated coronagraph imagery courtesy of LASCO C3 shows a coronal mass ejection (CME) leaving the sun and at least a portion of this cloud may be Earth directed. More updates to follow.

latest solar flare activity 2013 Aug 25

UPDATED 2013 Aug 25 

.24 hr Summary...
Solar activity was very low. There were no reportable flares this
period. All regions presently on the disk were either stable or
decaying. A disappearing filament was observed near N33W07 at
approximately 25/0800 UTC. No associated CME was visible at the
time of this report. The situation will be analyzed further if future 
imagery deems necessary.

.Forecast...
Solar activity is likely to be low (Below M1-Minor) for days one and two
(25 - 26 Aug) and expected to be very low with a chance for C-class
flare activity on day three (27 Aug).


Energetic Particle

.24 hr Summary...
The greater than 2 MeV electron flux at geosynchronous orbit was at
moderate to high levels, reaching a maximum flux value of 3,575 pfu at
24/1825 UTC. The greater than 10 MeV proton flux at geosynchronous
orbit was at background levels throughout the period.

.Forecast...
The greater than 2 MeV electron flux is expected to be at moderate to
high levels for the next three days (25 - 27 Aug). The greater than 10
MeV proton flux is expected to remain at background levels (Below
S1-Minor) for the next three days (25 - 27 Aug).


Solar Wind

.24 hr Summary...
Solar wind parameters, measured at the ACE spacecraft, decreased to near
background levels during the period. Speeds began at approximately 475
km/s reaching 400 km/s at the time of this report. Total field decreased
from 7 nT to 5 nT. IMF Bz was predominately positive until 25/0310 UTC,
when a positive (away) to negative (towards) solar sector boundary
crossing occurred. At that time Bz turned south and has remained at a
steady -3 nT.

.Forecast...
Solar wind speed is expected to remain steady around 400 km/s on day one
(25 Aug), before becoming enhanced on days two and three (26 - 27 Aug)
due to coronal hole high speed stream (CH HSS) effects.


Geospace

.24 hr Summary...
The geomagnetic field was at quiet levels.

.Forecast...
The geomagnetic field is expected to be quiet to unsettled (Below
G1-Minor) with a chance for isolated active conditions in the nighttime
sector on day one (25 Aug) due to prolonged negative Bz. The field is
expected to be predominately quiet to unsettled levels for days two and
three (26 - 27 Aug) due to CH HSS influence.

Latest Report of Solar flares and Geophysical Activity

Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 285 Issued at 2200Z on 11 Oct 2012

IA.  Analysis of Solar Active Regions and Activity from  10/2100Z
to 11/2100Z:  Solar activity was low.  Region 1589 (N12E49) was
responsible for the largest flare of the period; a C4 x-ray flare at
11/0804Z.  Region 1589 is currently the most complex region with a
Beta-Gamma magnetic classification.  New Region 1590 (S29E59)
rotated onto the southeast limb and was numbered today.  No
Earth-directed coronal mass ejections were observed.

IB.  Solar Activity Forecast:  Solar activity is expected to be low
with a chance for isolated M-class activity for the forecast period
(12-14 October).

IIA.  Geophysical Activity Summary 10/2100Z to 11/2100Z:
The geomagnetic field was quiet.  Solar wind speed, measured at the
ACE spacecraft, was slightly elevated between approximately 440 to
500 km/s while the Bz component of the interplanetary magnetic field
did not vary much beyond +/- 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 mostly quiet on days 1-2 (12-13 October).  On day 3
(14 October) a coronal hole high speed stream is expected to move
into geoeffective position causing quiet to unsettled conditions
with a chance for active periods.

Current Solar Flare Activity 2012

GEOMAGNETIC ACTIVITY CONTINUES: For the third day in a row, geomagnetic storms are circling the poles. In North America, auroras have spilled across the Canadian border descending as far south as Utah, Colorado, Kansas, and Nebraska. The best place to see the show, according to pilot Matt Melnyk, is from the window of an airplane.

Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 283 Issued at 2200Z on 09 Oct 2012

IA.  Analysis of Solar Active Regions and Activity from  08/2100Z
to 09/2100Z:  Solar activity was low. A few C-class events were
observed during the period, most from a region around the southeast
limb that has not yet rotated onto the disk.  Three new regions were
numbered today with Region 1589 (N13E75) as the largest and most
active.

IB.  Solar Activity Forecast:  Solar activity is expected to be low
with a chance for an isolated M-class flare over the next three days
(10-12 October).

IIA.  Geophysical Activity Summary 08/2100Z to 09/2100Z:
The geomagnetic field began the day at active levels before the onset
of two major storm periods (09/00-06Z). This peak activity was then
followed by a minor storm period before mostly quiet conditions
prevailed for the remainder of the period. The increased activity
was the result of residual effects from the CME on 05 October. 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 on day one (10 October), due to
high speed stream effects. Quiet to unsettled conditions are
forecast on day two (11 October) and mostly quiet levels are
expected on day three (12 October).

The storms were instigated by a CME strike on Oct. 8th and they are about to be re-energized by a solar wind stream due to hit Earth's magnetic field on Oct. 10th. NOAA forecasters estimate a 40% chance of strong geomagnetic storms during the next 24 hours, so high-latitude sky watchers should remain alert for auroras

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.

Latest solar flare report April 16 2012

Latest Solar Flare Report April 16 2012

The returning region off the northeast limb looks to be providing us with some Solar Fireworks. A massive eruption that registered as an M1.7 event, peaked at 17:45 UTC on Monday afternoon. This will most likely launch a blob of plasma into space. Due to the location of this event, the cloud will probably be directed away from Earth.

The active region off the northeast limb is now rotating into view and initially appeared to be spotless. Currently at 13:45 UTC a Sunspot is just now coming into view. We will get a better look at this region as the day progresses.

Sunspot 1455 which is turning closer to the western limb with every passing hour, did form some new spots on Sunday. This region may produce C-Class flares. Sunspot cluster 1459 in the southeast quadrant covers a large area but has yet to produce a noteworthy flare. There will remain a small risk for an M-Class event.

Solar Flare Impact in 2012

The Sun revolves at a 7.25 degree angle just like the Earth. However, due to its imperfect rotation behavior, the sun tends to "wobble", disrupting the internal core and making it highly unstable. The internal disruption eventually works its path to the outer surface and shoots out as a solar flare. Solar flares are little bits of the sun that launches out from the sun, giving off hazardous radiation and tremendous electrical power that go out into space like a bullet.

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.

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).

Strong Solar Flare from 1429 sunspot

Sunspot 1429 just generated another Coronal Mass Ejection and is seen in the latest Lasco C2 images. This explosion was much smaller than the event from last night, but should be a sign of things to come.

The Kp Index is creeping very close to the G1 Geomagnetic Storm Level. The Bz component of the Interplanetary Magnetic Field is tipped sharply south and combined with a gusty solar wind, Aurora at high latitudes will be possible tonight.

The solar wind speed has shown a gradual increase today. This gradual increase is expected to continue over the next 24-48 hours due to a solar sector boundary crossing. Minor geomagnetic activity will be possible at high latitudes.

Latest Report of Solar Flare and Geophysical Activity

Updated Mar 26 2200 UTC

Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 086 Issued at 2200Z on 26 Mar 2012

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 Update
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.

Old faithful Sunspot 1429, just produced a strong solar flare on the farside of the Sun. The time of the flare was around 22:45 UTC. This region is about 2 days away from returning onto the visible solar disk off the eastern limb. The image below shows the bright flash captured by STEREO Behind and a large, fast moving Coronal Mass Ejection (CME) was produced. Stay Tuned as we may be in for more activity in the weeks ahead.

Updated Mar 24 2200 UTC

Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 084 Issued at 2200Z on 24 Mar 2012

IA.  Analysis of Solar Active Regions and Activity from  23/2100Z
to 24/2100Z:  Solar activity was low.  A long duration C7/Sf flare
was observed from Region 1445 (S26E62) at 24/0901Z.  This flare was
accompanied by a Type II radio sweep (587 km/s).  A slow, weak CME
was later observed in STEREO-B COR2 imagery at 24/1025Z; plane of
sky speed was estimated to be about 400 km/s.  This CME is not
expected to be geoeffective.  A backsided CME was observed in
LASCO/C2 at 24/0036Z imagery with an estimated plane of sky speed of
700 km/s.  It appeared to originate from the vicinity of Old Region
1429.

IB.  Solar Activity Forecast:  Solar activity is expected to be low
with a chance for an isolated M-class event.

IIA.  Geophysical Activity Summary 23/2100Z to 24/2100Z:
The geomagnetic field ranged from quiet to active levels.  Active
levels were reached during 24/06-09Z  after a prolonged period of
southward Bz.  The remainder of the day saw quiet to unsettled
levels.  The solar wind speed measured at the ACE spacecraft
increased throughout the period, ending around 450 km/s.

IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be at predominantly quiet levels for the next three days
(25-27 March).
