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 072 Issued at 0245Z on 13 Mar 2001 This report is compiled from data received at SWO on 12 MarA. Energetic Events
Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep None
B. Proton Events
None
C. Geomagnetic Activity Summary
Quiet to unsettled with an
isolated active period during 12/1500 - 1800 UTC.
D. Stratwarm
Stratwarm alert exists Monday
As a result of the major warming, the circulation in the lower
stratosphere remains further disturbed leading to a reversed
temperature gradient up to 20 hpa. In the middle and upper
stratosphere, the cold and elongated polar vortex weakens. Slow
transition to summer conditions most probable.
