Report of latest solar flare activity April 20 2012

Despite the amount of large Sunspots on the Earth facing side of the Sun, solar activity has been fairly low over the past 24 hours. None of the current visible sunspots are magnetically complex (at this time). There will remain the chance for an isolated M-Class event. The sunspot totals are also helping to increase the daily Solar Flux readings. The solar flux ended near 140 on Thursday.

Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 110 Issued at 2200Z on 19 Apr 2012

IA.  Analysis of Solar Active Regions and Activity from  18/2100Z
to 19/2100Z:  Solar activity was low. The largest event of the period
was a C7 x-ray flare at 19/1126Z associated with Types II and IV
radio sweeps and a non-Earth-directed CME. This event may have
originated in old Region 1455 (N05, L=206), now about two days
beyond the west limb. Regions 1460 (N16W01) and 1463 (S26W49) each
produced a low-level C-class flare. Region 1460 showed spot growth
in its intermediate portion. Region 1462 (S24W31) produced a C1
flare at 19/1515Z associated with a CME that may have had an
Earthward component. Further analysis is required to determine if
the CME is likely to be geoeffective. New Region 1464 (N23E01,
Bxo-Beta) was numbered.

IB.  Solar Activity Forecast:  Solar activity is expected to be low
during days 1 - 3 (20 - 22 April) with a chance for an isolated
M-class flare.

IIA.  Geophysical Activity Summary 18/2100Z to 19/2100Z:
The geomagnetic field was quiet.

IIB.  Geophysical Activity Forecast:  Geomagnetic field activity is
expected to be at quiet to unsettled levels on day 1 (20 April) with
a chance for brief active levels due to a recurrent solar sector
boundary crossing. Quiet levels are expected during days 2- 3 (21 -
22 April).

Latest solar flare report April 17 2012

Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 108 Issued at 2200Z on 17 Apr 2012

IA. Analysis of Solar Active Regions and Activity from 16/2100Z
to 17/2100Z: Solar activity has been low for the past 24 hours. A
long duration C1 flare was observed from new Region 1461 (N13E66) at
17/0809Z. An associated CME became visible in LASCO C2 imagery at
17/0800Z but does not appear to be Earth-directed. A filament
eruption occurred at approximately 17/1330Z near N24W40. The
associated CME was first visible in LASCO C2 imagery at 17/1424Z but
is not expected to be geoeffective. New Region 1460 (N16E26) was
also numbered overnight and is considered a Dso-beta type spot
group. Region 1459 (S15E40) has shown a significant decrease in
areal coverage and is now a Dao-beta type spot group.

IB. Solar Activity Forecast: Solar activity is expected to be low
with a slight chance for an M-class flare for the next three days
(18-20 April).

IIA. Geophysical Activity Summary 16/2100Z to 17/2100Z:
The geomagnetic field was mostly quiet 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 mostly quiet on days one and two (18-19 April). Quiet
to unsettled conditions are expected with a chance for isolated
active periods on day three (20 April) due to a recurrent Solar
Sector Boundary Crossing (SSBC).

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.

Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 107 Issued at 2200Z on 16 Apr 2012

IA. Analysis of Solar Active Regions and Activity from 15/2100Z
to 16/2100Z: Solar activity was moderate during the past 24 hours.
An M1 flare was observed from a region around the east limb at
16/1745Z. Region 1459 (S15E56) continued to grow and is now
considered an Fhi-beta type group. A filament erupted at
approximately 16/1300Z near S43E33. The associated CME is not
expected to be geoeffective.

IB. Solar Activity Forecast: Solar activity is expected to be low
with a slight chance for M-class flares for the next three days
(17-19 April).

IIA. Geophysical Activity Summary 15/2100Z to 16/2100Z:
The geomagnetic field was quiet during the past 24 hours. 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 quiet for the next three days (17-19 April).

April 14 2012 Solar flare and Geophysical Activity

Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 105 Issued at 2200Z on 14 Apr 2012

IA. Analysis of Solar Active Regions and Activity from 13/2100Z
to 14/2100Z: Solar activity was very low. Region 1455 (N06W34)
produced occasional B-class x-ray flares during the first half of
the period. Region 1455 showed minor spot and penumbral decay during
the period and simplified from a beta-gamma to a beta magnetic
classification. New Regions 1458 (N07E70) and 1459 (S15E79) were
numbered. Neither were remarkable, but analysis was hampered due to
limb proximity. There were no Earth-directed CMEs observed during
the period.

IB. Solar Activity Forecast: Solar activity is expected to be very
low during days 1 - 3 (15 - 17 April) with a chance for isolated
C-class flares.

IIA. Geophysical Activity Summary 13/2100Z to 14/2100Z:
Geomagnetic field activity was at quiet to active levels. ACE solar
wind observations indicated the continued presence of a coronal hole
high-speed stream (CH HSS) with speeds in the 499 to 614 km/s range.
The greater than 2 MeV electron flux at geosynchronous orbit reached
high levels during the period.

IIB. Geophysical Activity Forecast: Geomagnetic field activity is
expected to be at quiet to unsettled levels on day 1 (15 April) with
a chance for active levels due to persistent CH HSS effects.
Activity is expected to decrease to mostly quiet levels during days
2 - 3 (16 - 17 April) as the CH HSS subsides.

Solar Wind Increase / Aurora Watch
The solar wind did show a gradual increase this morning to near 500 km/s and combined with a south tilting Bz component of the interplanetary magnetic field, geomagnetic activity at very high latitudes did increase. Visible Aurora is likely at high latitudes.

Aurora Watch: The Kp index continues to rise with the help of a high speed solar wind stream now near 550 km/s. The Bz has been pointing south at times and minor geomagnetic storming at high latitudes may soon be possible.

Updated 4/12/2012 @ 12:10 UTC
Solar Update / Farside Solar Flare
New Sunspot 1455 continues to grow but has only produced B-Class activity thus far. Another sunspot did form in the southern hemisphere and was numbered 1456. It looks to have already faded away. Existing sunspot 1454 located in the southeast quadrant remains stable. There will be a chance for a C-Class flare around AR11455.

Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 103 Issued at 2200Z on 12 Apr 2012

IA. Analysis of Solar Active Regions and Activity from 11/2100Z
to 12/2100Z: Solar activity has been at very low levels for the past
24 hours. Region 1455 (N06W05) has been the most active region
producing multiple B-class x-ray events. Region 1455 has shown rapid
growth in area and magnetic complexity, now a D-type beta group. New
Region 1456 (S20W19) was numbered today. Multiple CMEs were observed
during the period but none appear to be Earth directed.

IB. Solar Activity Forecast: Solar activity is expected to be at
very low levels with a chance for C-class activity for the next
three days (13 - 15 April) as Regions 1455 and 1456 continue to grow
and evolve.

IIA. Geophysical Activity Summary 11/2100Z to 12/2100Z:
The geomagnetic field has been at quiet to active levels over the
past 24 hours. Characteristics of an anticipated high speed solar
wind stream from a coronal hole were observed by the ACE spacecraft,
with subsequent elevated geomagnetic levels here at Earth.
Measurements from the ACE spacecraft showed an increase in solar
wind speeds from around 370 km/s to around 600 km/s with the total
IMF hovering around 12 nT.

IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be at unsettled to active levels with the chance for
minor storm periods on day one (13 April) as the effects of a
coronal hole high speed stream (CH HSS) continue. Quiet to unsettled
levels with a chance for active periods are expected on day two (14
April) as the effects of the CH HSS wane. Predominantly quiet levels
are expected on day three (15 April) as the geomagnetic field
returns to nominal levels.

Solar flare and Geophysical Activity update April 2012

Solar Update
Solar activity remains very low with only B-Class X-Ray activity detected mostly around Sunspot 1450 and region 1451. The leader spot located within 1450 did show some growth over the past 24 hours. There will be a chance for C-Class flares.

IA. Analysis of Solar Active Regions and Activity from 02/2100Z
to 03/2100Z: Solar activity has been very low for the past 24 hours.
Region 1450 (N16W04) produced two B4 flare events, one at 02/2220Z
and the other at 03/1228Z. A weak CME associated with a filament
eruption near N30E11, became visible on LASCO C2 imagery at
02/2348Z. This CME has a northerly trajectory and is not expected
to be geoeffective.

IB. Solar Activity Forecast: Solar activity is expected to be very
low with a chance for C-class flares for the next three days (04-06
April).

IIA. Geophysical Activity Summary 02/2100Z to 03/2100Z:
The geomagnetic field was at quiet levels for the past 24 hours.

IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be quiet to unsettled on days one and two (04-05 April)
due to a coronal hole high speed stream becoming geoeffective on 04
April, followed by the anticipated arrival of a weak CME associated
with the filament eruption that occurred at 02/0224Z. Day three (06
April) is expected to return to quiet levels.

SDF Number 091 Issued at 2200Z on 31 Mar 2012

IA. Analysis of Solar Active Regions and Activity from 30/2100Z
to 31/2100Z: Solar activity was low. A single C1/Sf flare was
observed from Region 1451 (N17E53) at 30/2112Z. New Region 1451 was
a simple Cro type group with a beta magnetic configuration. New
Region 1450 (N15E38) was also numbered and also a Cro type group
with beta magnetic characteristics. The remaining regions were
quiet and magnetically simple.

IB. Solar Activity Forecast: Solar activity is expected to be at
very low to low levels. An isolated C-class flare is likely with a
slight chance for an M-class event.

IIA. Geophysical Activity Summary 30/2100Z to 31/2100Z:
The geomagnetic field was at quiet levels. Solar wind speed measured at the ACE spacecraft ranged from around 450 km/s at the beginning of the period to 350 km/s at the end of the period. Bz was generally neutral. ACE data suggested a solar sector boundary crossing from negative to positive sector around 31/14Z.

IIB. Geophysical Activity Forecast: The geomagentic field is
expected to be predominantly quiet for the next three days (01-03
April).
