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 268 Issued at 2200Z on 24 SEP 1996IA. Analysis of Solar Active Regions and Activity from 23-2100Z to 24-2100Z
SOLAR ACTIVITY WAS VERY LOW. THE DISK IS SPOTLESS.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE
VERY LOW.
IIA. Geophysical Activity Summary 23-2100Z to 24-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED AS THE HIGH
SOLAR WIND SPEEDS HAVE ABATED IN THE PAST 24 HOURS. THE
GREATER THAN 2 MEV ELECTRON FLUX WAS HIGH.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE AT ACTIVE TO MINOR STORM LEVELS DURING THE
NEXT 24-36 HOURS AS ANOTHER HIGH SPEED STREAM IS ANTICIPATED.
THIS RECURRENT DISTURBANCE SHOULD END BY 27 SEPTEMBER.
