Solar activity 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 Report of Solar and Geophysical Activity
SDF Number 269 Issued at 2200Z on 25 SEP 1996IA. Analysis of Solar Active Regions and Activity from 24-2100Z to 25-2100Z SOLAR ACTIVITY WAS VERY LOW. THE DISK IS AGAIN
SPOTLESS.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE
VERY LOW.
IIA. Geophysical Activity Summary 24-2100Z to 25-2100Z
THE GEOMAGNETIC FIELD HAS BEEN QUIET TO UNSETTLED AT MID-
LATITUDES AND QUIET TO ACTIVE AT HIGH LATITUDES. ENERGETIC
ELECTRON FLUXES ATTAINED HIGH LEVELS DURING THE DAY.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE GENERALLY ACTIVE OVER THE NEXT 24 HOURS IN
RESPONSE TO A HIGH SPEED STREAM. UNSETTLED CONDITIONS SHOULD
DOMINATE THE LATTER PART OF THE FORECAST INTERVAL.
