Report of Solar and Geophysical Activity

Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 099 Issued at 2200Z on 08 Apr 2012

IA.  Analysis of Solar Active Regions and Activity from  07/2100Z
to 08/2100Z:  Solar activity was very low. Occasional B-class flares
occurred. A filament erupted from the northwest quadrant during
approximately 07/1825 - 1900Z. The eruption was associated with a
partial-halo CME with an estimated plane of sky speed of 690 km/s.
Most of the CME mass appeared to be directed southwestward of Earth
and is not expected to be significantly geoeffective. No new regions
were numbered.

IB.  Solar Activity Forecast:  Solar activity is expected to be very
low during days 1 - 3 (09 - 11 April) with a chance for an isolated
C-class flare.

IIA.  Geophysical Activity Summary 07/2100Z to 08/2100Z:
The geomagnetic field was quiet.

IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be at unsettled levels on day 1 (09 April) with a chance
for active levels due to a CME passage that is expected to begin
early in the day. There will also be a chance for minor storm levels
at high latitudes on day 1. Field activity is expected to decrease
to quiet to unsettled levels during days 2 - 3 (10 - 11 April).
