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 159 Issued at 2200Z on 07 JUN 1996IA. Analysis of Solar Active Regions and Activity from 06-2100Z to 07-2100Z SOLAR ACTIVITY WAS VERY LOW. REGION 7968
(N02W15), THE ONLY ACTIVE REGION CURRENTLY ON THE VISIBLE DISK,
HAS GROWN SIGNIFICANTLY IN BOTH SIZE AND NUMBER OF SPOTS SINCE
YESTERDAY. THIS REGION HAS PRODUCED THREE B-CLASS FLARES IN THE
LAST 24 HOURS, ONE AT 0956Z OPTICALLY CORRELATED AS A SUB-
FLARE. THE LARGE TWELVE DEGREE FILAMENT LOCATED AT N06E24
INCREASED IN WIDTH, LENGTH, AND DENSITY SINCE YESTERDAY, BUT
REMAINS RELATIVELY MOTIONLESS.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE
VERY LOW, WITH A 60% CHANCE FOR A C-CLASS EVENT AND 10% CHANCE
OF AN M-CLASS EVENT GENERATED FROM REGION 7968 DURING THE NEXT
24 HOURS.
IIA. Geophysical Activity Summary 06-2100Z to 07-2100Z
THE GEOMAGNETIC FIELD HAS BEEN AT QUIET LEVELS AT ALL LATITUDES
FOR THE PAST 24 HOURS. YESTERDAY'S ISOLATED ACTIVE TO MINOR
STORM CONDITIONS IS BELIEVED TO BE THE RESULT OF A DISAPPEARING
FILAMENT EARLIER IN THE WEEK.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED FOR THE NEXT 24 HOURS, WITH
AND INCREASED CHANCE OF ISOLATED ACTIVE PERIODS FOR DAYS TWO
AND THREE.
