Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 003 Issued at 2200Z on 03 Jan 2001
IA.  Analysis of Solar Active Regions and Activity from  02/2100Z
to 03/2100Z:  Solar activity was low. Several small C-class flares
occurred, many of which were optically uncorrelated to active
regions on the visible disk. The likely source of this activity
remains an area at, or beyond, the northeast limb. C-class subflares
also occurred in Regions 9289 (S07W25), 9290 (N29W60), and 9294
IB.  Solar Activity Forecast:  Solar activity is expected to be low.
Additional C-class activity is expected and there is a small chance
of an isolated M-class flare.
IIA.  Geophysical Activity Summary 02/2100Z to 03/2100Z:
The geomagnetic field ranged from quiet to active levels.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to range from quiet to active levels during the three-day
forecast period in response to a coronal hole stream.
