Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 149 Issued at 2200Z on 28 May 2012
IA. Analysis of Solar Active Regions and Activity from 27/2100Z
to 28/2100Z: Solar activity was very low. Region 1491 (N22W70)
produced a B7 flare at 28/1249Z, which was the largest flare of the
period. Region 1490 (S13E04) produced three nominal B-class flares
during the period. A CME associated with a filament eruption was
observed in LASCO C2 imagery at 28/0800Z off of the northwest
quadrant of the solar disk. The CME does not appear to be Earth
directed.
IB. Solar Activity Forecast: Solar activity is expected to be very
low to low for the next three days (29-31 May).
IIA. Geophysical Activity Summary 27/2100Z to 28/2100Z:
The geomagnetic field was quiet to unsettled. 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 for the next three days (29-31 May).
