Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 063 Issued at 2200Z on 04 Mar 2005
IA. Analysis of Solar Active Regions and Activity from 03/2100Z
to 04/2100Z: Solar activity was at very low levels. Region 471
(N12E70) is a newly numbered CSO beta group.
IB. Solar Activity Forecast: Solar activity is expected to be at
very low levels.
IIA. Geophysical Activity Summary 03/2100Z to 04/2100Z:
The geomagnetic field was at quiet levels.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be at quiet levels on 5 March. Isolated active
conditions may occur late on 6 March due to the onset of a recurrent
high speed coronal hole stream. Isolated minor storm conditions are
possible on 7 March due to the continued effects from the high speed
stream.
