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 2002 This report is compiled from data received at SWO on 14 JanA. Energetic Events
Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 0120 0136 0144 9775 S07W52 M1.0 Sf 0152 0156 0203 9782 N05E44 M1.7 2n 140 0529 0627 0825 M4.4 II 2235 2246 2258 9775 S05W65 M1.1 Sf
B. Proton Events
Particle fluxes for >10MeV protons were enhanced,
but remained below event thresholds.
C. Geomagnetic Activity Summary
The geomagnetic field was quiet to
unsettled. High speed stream effects from a favorably positioned
coronal hole appeared to wane, with falling solar wind velocities
over the course of the period. Particle fluxes for >2MeV electrons
were enhanced, but remained below event thresholds.
D. Stratwarm
