Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 087 Issued at 2200Z on 27 Mar 2012
IA. Analysis of Solar Active Regions and Activity from 26/2100Z
to 27/2100Z: Solar activity has been at low levels. Region 1444
(N21W17) produced a C5/1f flare at 27/0308Z. Region 1442 (N12W13)
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).
