Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 052 Issued at 2200Z on 21 Feb 2008
IA. Analysis of Solar Active Regions and Activity from 20/2100Z
to 21/2100Z: Solar activity was at very low levels. The visible
solar disk remained spotless.
IB. Solar Activity Forecast: Solar activity is expected to continue
at very low levels.
IIA. Geophysical Activity Summary 20/2100Z to 21/2100Z:
The geomagnetic field was at mostly quiet levels. From 21/1200 -
1500Z, an isolated unsettled period was observed. This increase in
activity was due to sustained southward Bz. The greater than 2 MeV
electron flux at geosynchronous orbit reached high levels again
today.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to remain at predominately quiet levels throughout the
forecast period (22 - 24 February).
