Joint USAF/NOAA Solar and Geophysical Activity Summary

SGAS Number 088 Issued at 0245Z on 29 Mar 2003 This report is compiled from data received at SWO on 28 Mar

B. Proton Events
None
C. Geomagnetic Activity Summary
The geomagnetic field was mostly quiet to active with isolated minor storm periods during local nighttime hours. The most active conditions early in the period were due to a waning high speed coronal hole stream. A weak transient passed the ACE spacecraft between 28/1400 - 1500Z. Predominantly southward Bz in the IMF resulted in active levels late in the period.
D. Stratwarm
None

F. Comments
  The greater than 2 MeV electron fluxes at
geosynchronous orbit reached high levels.
