Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 079 Issued at 2200Z on 20 Mar 2009
IA.  Analysis of Solar Active Regions and Activity from  19/2100Z
to 20/2100Z:  Solar activity was very low. The visible disk remains
spotless. No flares were observed.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 19/2100Z to 20/2100Z:
Geomagnetic field activity was at quiet levels. The solar wind speed
has increased from 290 to 380 Km/sec due to a coronal hole high
speed stream. The Bz has ranged from -5 to +7nT.
IIB.  Geophysical Activity Forecast:  Geomagnetic field activity is
expected to be quiet to unsettled for day one (21 March). Activity
will return to quiet for days two and three (22-23 March).
