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. UPDATE #2 @ 00:45 UTC (Sep 5): Proton levels continue to rise following the eruption around 2673 earlier this evening. A minor (S1) radiation storm is currently in progress.

Solar and Geophysical Activity 22 Jun 2012

IA.  Analysis of Solar Active Regions and Activity from  20/2100Z
to 21/2100Z:  Solar activity was very low.  Region 1504 (S15W89)
produced a long duration B7 flare at 21/1814Z which was the largest
event of the period.  There were no Earth-directed CMEs observed
during the period.

IB.  Solar Activity Forecast:  Solar activity is expected to be
predominantly very low for the next three days.  There is a chance
for an isolated C-class flare from Region 1504 on day 1 (22 June) as
it approaches the west limb.

IIA.  Geophysical Activity Summary 20/2100Z to 21/2100Z:
The geomagnetic field was quiet. The greater than 2 MeV electron flux
at geosynchronous orbit was at high levels throughout the period.

IIB.  Geophysical Activity Forecast:  Geomagnetic activity is
expected to be quiet on 22-24 June.

Latest Solar Flare Activity Update April 27 2012

Solar Update
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).

Latest Solar Flare Activity april 27 2012

Sunspot 1466 located in the northern hemisphere, produced an M1.0 Solar Flare at 08:24 UTC Friday morning. Despite all of the Sunspots this month, this was only the second M-Class flare in April.

Potential Impacts: Satellite systems may experience significant charging resulting in increased risk to satellite systems.

FARSIDE ACTIVITY: For more than a week, solar activity has been low. On April 26th around 0600 UT, an active region on the farside of the sun broke the calm with a powerful eruption. NASA's Solar Dynamics Observatory recorded a massive cloud of plasma flying over the sun's southwestern limb:

The same active region has since hurled three CMEs into space. The clouds will certainly miss Earth, but they might hit Mercury, which appears to be in the line of fire.
