Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 091 Issued at 2200Z on 01 Apr 2010
IA.  Analysis of Solar Active Regions and Activity from  31/2100Z
to 01/2100Z:  Solar activity has been very low.  Region 1057 (N15W45)
continues a slow decay.  Region 1059 (S22E10) remains stable.  An
eleven degree filament disappeared near N26W31, between
01/0030-1355Z. No flares were observed during the past 24 hours.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 31/2100Z to 01/2100Z:
The geomagnetic field has been at quiet to active conditions.  The
ACE spacecraft indicated the signature of a weak coronal hole high
speed stream.  Solar wind speed averaged approximately 410 km/s with
IMF Bz ranging between -7/+8 nT.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be predominately quiet for the next three days (02-05
April).
