Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 150 Issued at 2200Z on 29 May 2012
IA.  Analysis of Solar Active Regions and Activity from  28/2100Z
to 29/2100Z:  Solar activity was very low during the past 24 hours.
Region 1492 (S13E18) remained the largest spot group on the disk,
but showed decay and did not produce any notable events. All other
regions on the disk were quiet and stable. No Earth-directed CMEs
were observed during the period.
IB.  Solar Activity Forecast:  Solar activity is expected to remain
very low with C-class events likely for the next three days (30 May
- 01 June).
IIA.  Geophysical Activity Summary 28/2100Z to 29/2100Z:
The geomagnetic field was mostly quiet during the past 24 hours. 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 (30 May - 01
June).
