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 180 Issued at 2200Z on 28 JUN 1996IA. Analysis of Solar Active Regions and Activity from 27-2100Z to 28-2100Z SOLAR ACTIVITY WAS VERY LOW. NO FLARES OCCURRRED.
TWO ACTIVE REGIONS, 7976 (N13W02) AND 7973 (N08W48), REMAIN ON
THE VISIBLE DISK. THE SINGLE 'HSX' SPOT IN REGION 7973 HAS
REMAINED ESSENTIALLY UNCHANGED SINCE IT FIRST ROTATED ONTO THE
DISK 9 DAYS AGO. A SMALL DSF NOTED IN THIS REGION EARLY IN
THE REPORTING PERIOD HAS BEGUN TO REFORM IN ITS ORIGINAL
LOCATION. REGION 7976 CONTINUES AS A FAIRLY STABLE FOUR
SPOT 'HRX' GROUP. AN EXTENSIVE BRIGHT FACULAE FIELD CENTERED
AT N24E63 HAS THE POTENTIAL TO DEVELOP INTO AN ACTIVE REGION,
ALTHOUGH NO SPOTS ARE CURRENTLY VISIBLE.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE
VERY LOW, WITH A 10% CHANCE OF A C-CLASS EVENT FROM REGION
7976.
IIA. Geophysical Activity Summary 27-2100Z to 28-2100Z
THE GEOMAGNETIC FIELD HAS BEEN AT QUIET TO UNSETTLED
LEVELS FOR THE PAST 24 HOURS.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET, WITH ISOLATED PERIODS OF UNSETTLED
CONDITIONS, FOR THE NEXT THREE DAYS.
