Joint USAF/NOAA Solar and Geophysical Activity Summary
SGAS Number 356 Issued at 0245Z on 22 Dec 2003
This report is compiled from data received at SWO on 21 Dec
A.  Energetic Events
Begin  Max  End  Rgn   Loc   Xray  Op 245MHz 10cm   Sweep
None
B.  Proton Events:  None
C.  Geomagnetic Activity Summary:  The geomagnetic field was
unsettled to active. This disturbance is due to an elongated
transequatorial coronal hole which rotated into a geoeffective
position on 20 December. Solar wind speed is now elevated to over
600 km/s, but predominantly northward IMF Bz is thwarting a more
significant response in the geomagnetic field.
D.  Stratwarm:  STRATWARM ALERT / SUNDAY / STRATWARM EXISTS.
INTENSE WARMING OVER SIBERIA / EUROPE CONTINUES IN THE UPPER
STRATOSPHERE.
E.  Daily Indices: (real-time preliminary/estimated values)
