Geophysical report
Any mentioned solar flare in this report has a scaling factor applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor, solar flares are reported as 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.

Joint USAF/NOAA Solar and Geophysical Activity Summary
SGAS Number 139 Issued at 0245Z on 19 May 2003 This report is compiled from data received at SWO on 18 MayA. 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 quiet to
unsettled. Slightly enhanced solar wind conditions occurred late in
the period and produced the unsettled conditions.
D. Stratwarm
None
