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 015 Issued at 0245Z on 15 Jan 2003 This report is compiled from data received at SWO on 14 Jan

B. Proton Events
None
C. Geomagnetic Activity Summary
The geomagnetic field was quiet to unsettled with isolated active periods at higher latitudes. A period (04-12Z) of mostly southward orientation in the IMF was responsible for the more disturbed periods.
D. Stratwarm
STRATWARM ALERT/TUESDAY/STRATWARM EXISTS. NEW WARM PULS, STRONGEST IN THE UPPER STRATOSPHERE, BUT TEMPERATURE HAS INCREASED MORE THAN 30 KELVIN ALSO AT 10 HPA AND BELOW WITHIN ONE WEEK OVER NORTHERN SIBERIA. REVERSAL OF THE TEMPERATURE GRADIENT BETWEEN 60N AND THE NORTH POLE EXPECTED WITHIN THE NEXT 3 DAYS FROM 50H PA UP 1HPA.
