Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 244 Issued at 2200Z on 01 Sep 2010
=======================================================================
IA.  Analysis of Solar Active Regions and Activity from  31/2100Z
to 01/2100Z:  Solar activity has been at very low levels for the past
24 hours. Region 1101 (N12W32) and Region 1102 (N26W52) grew in
areal coverage but remained stable and quiet. New Regions 1103
(N25W32) and 1104 (N24W27) developed late in the period and are both
magnetically classified as beta groups.
=======================================================================
IB.  Solar Activity Forecast:  Solar activity is expected to be at
very low levels with a slight chance for C-class events for the next
three days (02-04 September).
=======================================================================
IIA.  Geophysical Activity Summary 31/2100Z to 01/2100Z:
The geomagnetic field has been at quiet levels for the past 24 hours.
The greater than 2 MeV electron flux at geosynchronous orbit was at
high levels throughout the period.
=======================================================================
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be at quiet levels for the next three days (02-04
September).
