C-Class Flare and CME
A couple of new sunspots are rotating into view off the eastern limb. One of these regions located off the northeast limb produced a C3.7 Solar Flare at 07:45 UTC this morning and was associated with a Type II Sweep Frequency Event and CME. Due to the spots location, the plasma cloud should be directed mostly towards the east.
ALERT: Type II Radio Emission
Begin Time: 2012 Apr 24 0748 UTC
Estimated Velocity: 1029 km/s
Description: Type II emissions occur in association with eruptions on the sun and typically indicate a coronal mass ejection is associated with a flare event.
IA. Analysis of Solar Active Regions and Activity from 22/2100Z
to 23/2100Z: Solar activity has been at low levels for the past 24
hours. There are currently 8 active regions on the disk, with 5
regions having sunspots. The spotted regions on the disk all
remained rather quiet and stable throughout the period. However,
around plage Region 1461 (N10W19), two C-class events were observed
today with associated Earth directed CMEs.
IB. Solar Activity Forecast: Solar activity is expected to be at
low levels with a chance for M-class x-ray events for the next three
days (24 - 26 April).
IIA. Geophysical Activity Summary 22/2100Z to 23/2100Z:
The geomagnetic field has been at quiet to minor storm levels for the
past 24 hours. Observations made by the ACE spacecraft, around
23/0200Z, indicated the arrival of a CME that lifted off the solar
disk on 19 April. Solar wind velocities increased from 350 - 400
km/s with the total IMF reaching around 18 nT. The Boulder
magnetometer measured a 31 nT sudden impulse at 23/0325Z in
conjunction with the CME arrival here at Earth. From then on, active
to minor storm levels were observed due to multiple periods of
sustained negative Bz.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be at quiet to active levels with a slight chance for a
minor storm on day 1 (24 April) as effects from the CME wane and a
coronal hole high speed stream (CH HSS) moves in. Quiet to active
levels are expected on day two (25 April) as the effects of the CH
HSS continue. An increase to quiet to minor storm levels are
expected on day three (26 April) as the two CMEs, observed earlier
in the period, are expected to become geoeffective.

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 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.

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.

expected to be quiet for the next three days (17-19 April).

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.

Latest Report of Solar flares and Geophysical Activity
Joint USAF/NOAA Report of Solar and Geophysical Activity
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).
