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 056 Issued at 0245Z on 25 Feb 2015 This report is compiled from data received at SWO on 24 FebA. Energetic Events
Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep None
B. Proton Events
None.
C. Geomagnetic Activity Summary
The geomagnetic field reached
minor storm conditions during the 24/0300 and 24/0600 UTC synoptic
periods in response to the high speed solar wind stream. The
remainder of the period saw a wane from active to quiet conditions.
