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 161 Issued at 2200Z on 09 JUN 1996IA. Analysis of Solar Active Regions and Activity from 08-2100Z to 09-2100Z SOLAR ACTIVITY WAS VERY LOW. NEW REGION 7971
(S07W42), A TWO SPOT 'BXO' GROUP, WAS NUMBERED TODAY.
REGION 7968 (N02W42) PRODUCED TWO B-CLASS EVENTS, THE LARGEST
A B7 AT 09/0910Z, WHICH WERE BOTH OPTICALLY CORRELATED AS
SUBFLARES. REGION 7968 HAS LOST A NUMBER OF SPOTS SINCE
YESTERDAY, BUT ITS OVERALL SIZE HAS REMAINED FAIRLY CONSTANT,
AND IS CURRENTLY A 'CAO' GROUP WITH 12 SPOTS.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE
VERY LOW, ALTHOUGH REGION 7968 REMAINS ACTIVE WITH A 40% CHANCE
OF GENERATING A C-CLASS EVENT AND 10% CHANCE OF GENERATING AN
M-CLASS EVENT.
IIA. Geophysical Activity Summary 08-2100Z to 09-2100Z
THE GEOMAGNETIC FIELD HAS BEEN AT QUIET LEVELS AT ALL
LATITUDES FOR THE PAST 24 HOURS.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED FOR THE NEXT THREE DAYS,
WITH AN INCREASED CHANCE OF ISOLATED PERIODS OF ACTIVE
CONDITIONS ON DAYS TWO AND THREE.
