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 007 Issued at 0245Z on 07 Jan 2001 This report is compiled from data received at SWO on 06 JanA. Energetic Events
Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 2247 2247 2247 140
B. Proton Events
There was an enhancement in the greater than 10
MeV protons at geosynchronous orbit that began late on 05 January.
These particles may be an effect of a large halo CME directed away
from earth seen by LASCO at 1706 UTC yesterday.
C. Geomagnetic Activity Summary
The geomagnetic field was quiet to
unsettled.
