Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 301 Issued at 2200Z on 27 Oct 2004
IA.  Analysis of Solar Active Regions and Activity from  26/2100Z
to 27/2100Z:  Solar activity continued at low levels. Isolated small
C-class events occurred, primarily from Region 687 (N12W24). Newly
numbered Region 693 (S13E72) rotated into view with a small field of
bright plage. The LASCO Coronagraph observed a near halo CME,
apparently from the backside at approximately 1200 UTC.
IB.  Solar Activity Forecast:  Solar activity is expected to persist
at low levels.
IIA.  Geophysical Activity Summary 26/2100Z to 27/2100Z:
The geomagnetic field was quiet.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet to mildly unsettled for the next 72 hours.
