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 063 Issued at 0245Z on 04 Mar 2002 This report is compiled from data received at SWO on 03 MarA. Energetic Events

B. Proton Events
None
C. Geomagnetic Activity Summary
The geomagnetic field was mostly
quiet to unsettled, with a single active period during 03/2100-2400
UTC. Sustained southward IMF with increasing density and velocity,
probably resulting from a CIR ahead of an expected onset of high
speed stream effects, is the likely cause of the active period.
D. Stratwarm
STRATWARM ALERT EXISTS STRATWARM SUNDAY
Throughout the stratosphere, still disturbed circulation pattern with
the warm air over the polar region and Asia and a displaced vortex
over northern Siberia, leading to a reversed temperature gradient
between the pole and 60N from 100HPa up to 1Hpa
