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 066 Issued at 2200Z on 07 MAR 1997IA. Analysis of Solar Active Regions and Activity from 06-2100Z to 07-2100Z SOLAR ACTIVITY WAS VERY LOW. A SMALL TRAILER SPOT IN
REGION 8020 (N09E62) BECAME VISIBLE TODAY, MAKING THE GROUP A SIMPLE
CAO CLASS GROUP. THE REGION WAS VERY QUIET AND STABLE FOR THE PAST
24 HOURS. NO FLARES HAVE BEEN OBSERVED DURING THE REPORTING PERIOD,
AND YESTERDAY'S TYPE III RADIO SWEEP ACTIVITY HAS BEEN SIGNIFICANTLY
REDUCED TODAY.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE VERY
LOW FOR THE NEXT THREE DAYS.
IIA. Geophysical Activity Summary 06-2100Z to 07-2100Z
THE GEOMAGNETIC FIELD WAS PREDOMINANTLY QUIET TO UNSETTLED FOR THE
PAST 24 HOURS. AN INTERVAL OF SOMEWHAT ELEVATED ACTIVITY OCCURRED
FROM 0900Z-1600Z: MID-LATITUDES WERE UNSETTLED AND HIGH LATITUDE
SITES WERE AT UNSETTLED TO ACTIVE LEVELS.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE PREDOMINANTLY UNSETTLED FOR THE NEXT THREE DAYS.
THERE WILL BE AN INCREASED LIKELIHOOD FOR OCCASIONAL ACTIVE PERIODS
LATE ON THE THIRD DAY BECAUSE A CORONAL HOLE WILL BE ROTATING INTO A
FAVORABLE POSITION AT THAT TIME.
