Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 079 Issued at 2200Z on 20 Mar 2010
IA.  Analysis of Solar Active Regions and Activity from  19/2100Z
to 20/2100Z:  Solar activity was very low. Region 1054 (N16W82) has
decayed to an Axx Alpha spot and has been quiet. Region 1056
(N18E07) remains stable and quiet as a Bxo Beta region. A fast
moving CME that overtook the CME from 19 March is visible off the
west limb on LASCO C3.
IB.  Solar Activity Forecast:  Solar activity is expected to remain
very low for the next 3 days (21-23 March).
IIA.  Geophysical Activity Summary 19/2100Z to 20/2100Z:
The geomagnetic field was mostly quiet with a brief period of
unsettled to active conditions (03-09Z) due to extended Bz south and
slightly elevated solar wind speeds near 420km/s.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to remain quiet with brief periods of unsettled conditions
over the next 3 days (21-23 March).
