Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 084 Issued at 2200Z on 24 Mar 2008
IA. Analysis of Solar Active Regions and Activity from 23/2100Z
to 24/2100Z: Solar activity was at very low levels. Region 987
(S08E36) has grown in area and spot number over the summary period.
New Region 988 (S09E59) was numbered today. Both of these regions
are D-type spot groups with beta magnetic configurations. Multiple
B-class events have occurred from these regions, as well as a region
that is on the east limb.
IB. Solar Activity Forecast: Solar activity is expected to be at
very low to low levels. There is a chance for isolated C-class
flares from Regions 987 and 988.
IIA. Geophysical Activity Summary 23/2100Z to 24/2100Z:
The geomagnetic field was at quiet levels.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be at mostly quiet to unsettled levels on day one (25
March). On days two and three (26 and 27 March) an increase to
unsettled to active levels is expected due to a coronal hole high
speed stream rotating into a geoeffective position. During this
period isolated minor storm levels at middle latitudes and major
storm conditions at high latitudes are possible.
