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.
Solar and Geophysical Activity Summary 2003 Feb 10 0245 UTCPrepared by the NOAA © SWPC and processed by SpaceWeatherLive.com
Joint USAF/NOAA Solar and Geophysical Activity Summary
SGAS Number 041 Issued at 0245Z on 10 Feb 2003 This report is compiled from data received at SWO on 09 FebA. 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 mostly
quiet to unsettled with isolated active periods. Solar wind
conditions were at near nominal levels, but periods of weak
southward IMF Bz yielded the occasional active periods.
D. Stratwarm
STRATWARM ALERT / SUNDAY / STRATWARM EXISTS.
IN THE MIDDLE AND UPPER STRATOSPHERE, STILL DISTURBED TEMPERATURE
DISTRIBUTION WITH A DECAYING WARM REGION OVER NORTHERN SIBERIA WHICH
STILL LEADS TO A REVERSED TEMPERATURE GRADIENT BETWEEN 60N AND THE
POLE FROM 3 TO1 HPA.

F. Comments
The greater than 2 MeV electron fluxes at geosynchronous orbit remain considerably enhanced, reaching high levels again this period.
