Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 052 Issued at 2200Z on 21 Feb 2012
IA. Analysis of Solar Active Regions and Activity from 20-2100Z to 21-2100Z
Solar activity was low. There was one C-class flare
during the past 24 hours, a C1 at 21/1148Z from Region 1422
(N15W24). This region continues to be the largest group on the
disk.
IB. Solar Activity Forecast
Solar activity is expected to be low.
IIA. Geophysical Activity Summary 20-2100Z to 21-2100Z
The geomagnetic field has been quiet to unsettled. ACE data has
shown a steady decline in solar wind speed. The greater than 2 MeV
electron flux at geosynchronous orbit reached high levels during the
period.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet for the next 36 hours. An increase to
unsettled levels is expected mid-day on 23 February and continuing
through 24 February due to a coronal hole high speed stream.
