Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 077 Issued at 2200Z on 18 Mar 2009
IA.  Analysis of Solar Active Regions and Activity from  17/2100Z
to 18/2100Z:  Solar activity was very low. The solar disk remains
spotless. No flares were observed.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 17/2100Z to 18/2100Z:
Geomagnetic field activity was at quiet levels. The greater than 2
MeV electron flux at geosynchronous orbit reached high levels again.
IIB.  Geophysical Activity Forecast:  Geomagnetic field activity is
expected to be quiet on day 1 (19 March). Activity is expected to
increase to quiet to unsettled levels during days 2 to 3 (20-21
March).
