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 020 Issued at 0245Z on 20 Jan 2003 This report is compiled from data received at SWO on 19 JanA. Energetic Events

None
C. Geomagnetic Activity Summary
The geomagnetic field was at quiet
to active levels. Active conditions commenced with an increase in
the solar wind speed to approximately 600 km/sec, believed to be
associated with coronal hole effects from the southern polar
extension whose leading edge is at about W53..
D. Stratwarm
STRATWARM ALERT/SUNDAY/STRATWARM EXISTS.
WARMING CONTINUES OVER THE POLAR REGION, BUT CONSIDERABLE WEAKENING.
REVERSED TEMPERATURE GRADIENT BETWEEN 60N AND THE POLE UP TO 2 HPA
AND EASTERLY WINDS AT 60N TO 1 HPA.
