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.
Solar and Geophysical Activity Summary 2002 Jan 16 0245 UTCPrepared by the NOAA © SWPC and processed by SpaceWeatherLive.com
Joint USAF/NOAA Solar and Geophysical Activity Summary
SGAS Number 016 Issued at 0245Z on 16 Jan 2002 This report is compiled from data received at SWO on 15 JanA. Energetic Events
Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep None
B. Proton Events
Particle flux for >10MeV protons reached event
level of 10 pfu at 15/1435 UTC, and the event remains in progress
with a current flux of about 12 pfu. The slow enhancement in proton
flux is likely from a west limb CME on 14 January, with the delay in
proton enhancement due to the intervening effects of a coronal hole
high speed stream.
C. Geomagnetic Activity Summary
The geomagnetic field was quiet.
Particle fluxes for >2MeV electrons reached event level during the
period. >2MeV electrons briefly exceeded 1000 pfu at geosynchronous
orbit near local noon, as measured on GOES-8, during 15/1405-1615
UTC.
