Joint USAF/NOAA Solar and Geophysical Activity Summary

SGAS Number 090 Issued at 0245Z on 31 Mar 2003 This report is compiled from data received at SWO on 30 Mar
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 with isolated minor storm periods at high latitudes. Solar wind signatures early this period indicate a transition from transient flow to a high speed coronal hole stream. Solar wind speed began the period near 400 km/s, but gradually increased to near 650 km/s by end of period.
D. Stratwarm
STRATWARM ALERT / SUNDAY / STRATWARM EXISTS A LARGE WARM REGION OVER ASIA INTENSIFIES AND MOVES POLEWARDS WHILE THE COLD REGION WEAKENS, INDICATING THE BEGINNING OF THE FINAL WARMING.
