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 Jan

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.
