Joint USAF/NOAA Solar and Geophysical Activity Summary

SGAS Number 142 Issued at 0245Z on 22 May 2003 This report is compiled from data received at SWO on 21 May

B. Proton Events
None
C. Geomagnetic Activity Summary
The geomagnetic field was at quiet to active levels. Periods of southward Bz near -10 nT resulted in two active periods during the day. Solar wind speed began a steady increase, most likely due to the onset of an equatorial coronal hole high speed flow. Wind speed increased from 400 km/s to over 600 km/s and continues to rise.
