SDF Number 023 Issued at 2200Z on 23 Jan 2010
IA. Analysis of Solar Active Regions and Activity from 22/2100Z
to 23/2100Z: Solar activity has been at very low levels for the past
24 hours. Isolated low level B-flares were observed. Region 1041
(S24E35) is now classified as a Eai-beta with 9 spots. Region 1042
(N22W42) is now classified as a Cao-beta with 11 spots. No new
regions were numbered today.
IB. Solar Activity Forecast: Solar activity is expected to remain
at very low to low levels with a slight chance for an isolated
M-flare.
IIA. Geophysical Activity Summary 22/2100Z to 23/2100Z:
The geomagnetic field was predominantly quiet for the past 24 hours.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to remain at quiet levels for the next three days (24-26
January).
