Joint USAF/NOAA Solar and Geophysical Activity Summary

SGAS Number 089 Issued at 0245Z on 30 Mar 2003 This report is compiled from data received at SWO on 29 Mar
A. Energetic Events
Begin  Max  End  Rgn   Loc   Xray  Op 245MHz 10cm   Sweep
1831 1839 1846  0318 S13W21 C8.2  1f 170    25
B. Proton Events
None
C. Geomagnetic Activity Summary
The geomagnetic field ranged from quiet to minor storm levels. A pronounced transient flow with sustained periods of southward Bz in the interplanetary magnetic field, produced the disturbed periods. Solar wind speed decreased to less than 400 km/s by end of period, but continued southward Bz is prolonging the disturbance.
