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.
