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 235 Issued at 2200Z on 22 AUG 1996IA. Analysis of Solar Active Regions and Activity from 21-2100Z to 22-2100Z SOLAR ACTIVITY WAS LOW. A C3 X-RAY EVENT OCCURED
AT 22/0845Z ACCOMPANIED BY TYPES II AND IV SPECTRAL RADIO
BURSTS. THIS ACTIVITY WAS FOLLOWED BY A LONG DURATION C4 X-RAY
EVENT WHICH PEAKED AT 22/1003Z. NONE OF THIS ACTIVITY WAS
OPTICALLY CORRELATED. THIS ACTIVITY IS PROBABLY RELATED TO THE
RETURN OF OLD REGION 7981 AT THE SOUTHEAST LIMB.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE
VERY LOW. THE POSSIBILITY OF A C-CLASS FLARE DOES EXIST WITH
THE RETURN OF REGION 7981.
IIA. Geophysical Activity Summary 21-2100Z to 22-2100Z
THE GEOMAGNETIC FIELD HAS BEEN AT QUIET LEVELS FOR THE PAST
24 HOURS.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS
