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 046 Issued at 0245Z on 15 Feb 2003 This report is compiled from data received at SWO on 14 Feb
A. Energetic Events
Begin  Max  End  Rgn   Loc   Xray  Op 245MHz 10cm   Sweep
0907 0918 0923  0284 N13W86 M1.2  Sf
B. Proton Events
None
C. Geomagnetic Activity Summary
The geomagnetic field was at quiet to active levels. Early in the period the solar wind speed began a gradual increase to a current 500 km/s rise, this, along with frequent periods of southward Bz allowed for the active conditions. The greater than 2 MeV electron fluxes at geosynchronous orbit reached moderate levels today.
D. Stratwarm
STRATWARM ALERT / FRIDAY / STRATWARM EXISTS. IN THE MIDDLE AND UPPER STRATOSPHERE, STILL SLIGHTLY DISTURBED TEMPERATURE DISTRIBUTION WITH A WARM REGION OVER SIBERIA LEADING TO A REVERSED TEMPERATURE GRADIENT BETWEEN 60N AND THE POLE AT 10 AND 1 HPA.
