Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 083 Issued at 2200Z on 23 Mar 2012
IA. Analysis of Solar Active Regions and Activity from 22/2100Z
to 23/2100Z: Solar activity was moderate. Newly numbered Region
1445 (S24E76) rotated onto the solar disk and produced an M1 flare
at 23/1940Z as well as a C6 flare at 23/1639Z. Region 1444 (N21E37)
was numbered overnight, but is small and stable.
IB. Solar Activity Forecast: Solar activity is expected to be low
to moderate, mainly due to additional activity from Region 1445.
IIA. Geophysical Activity Summary 22/2100Z to 23/2100Z:
The geomagnetic field was initially unsettled, but decreased to quiet
levels after 23/0300Z. The elevated activity was caused by a solar
sector boundary crossing. 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 three days (24-26 March).
