Joint USAF/NOAA Solar and Geophysical Activity Summary

SGAS Number 307 Issued at 0245Z on 03 Nov 2003 This report is compiled from data received at SWO on 02 Nov

B. Proton Events
The greater than 10 MeV proton fluxes reached alert levels at 02/1105Z and were initially believed to have been from the M3 event earlier in the period (early maximum was 30 pfu). Since the X8 event they have seen a maximum of 1510 pfu at 02/2305Z. The greater than 100 MeV proton fluxes have also reached alert levels due to the X8 event; at 1740 (15 minutes from the flare maximum) they pushed through event threshold and have since seen a maximum of 49 pfu at 02/1915Z.
C. Geomagnetic Activity Summary
The geomagnetic field was at unsettled to minor storm levels. Isolated minor storm conditions are likely due to the continued elevated solar wind speeds and the occasional southward Bz in the interplanetary magnetic field.
