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 025 Issued at 0245Z on 25 Jan 2012 This report is compiled from data received at SWO on 24 JanA. Energetic Events
Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 0332 0332 0332 120
B. Proton Events
Proton levels are high. The greater than 10 MeV
proton flux event that began at 23/0530Z, reached a new maximum of
6310 pfu at 24/1530Z. Flux values since the onset of this event
have decreased below 1000 pfu and are currently at 744 pfu.
C. Geomagnetic Activity Summary
The geomagnetic field was at quiet
to active levels with isolated minor to major storm periods.
