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 315 Issued at 2200Z on 11 NOV 1997IA. Analysis of Solar Active Regions and Activity from 10-2100Z to 11-2100Z SOLAR ACTIVITY REMAINED LOW. REGION 8103 (N18W84)
GENERATED FOUR ADDITIONAL C-CLASS X-RAY EVENTS IN THE PAST 24 HOURS,
THE LARGEST A C4/SF AT 11/0727. REGION 8106 (N27W44) WAS NUMBERED
YESTERDAY, BUT WAS NOT OFFICIALLY CLASSIFIED UNTIL TODAY DUE TO
POOR/INCONSISTENT SEEING AT THE ONSERVING STATIONS. REGION 8106 IS
CURRENTLY A 5-SPOT 'CSO' BETA GROUP.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE VERY
LOW TO LOW. REGION 8103 COULD GENERATE ADDITIONAL C-CLASS
EVENTS AS IT DEPARTS THE WEST LIMB. REGION 8106 HAS ALSO SHOWN THE
POTENTIAL FOR C-CLASS ACTIVITY.
IIA. Geophysical Activity Summary 10-2100Z to 11-2100Z
THE GEOMAGNETIC FIELD HAS BEEN QUIET FOR THE PAST 24 HOURS, EXCEPT
FOR A SINGLE PERIOD OF UNSETTLED CONDITIONS DURING THE INTERVAL
11/0300-0600Z.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE MOSTLY QUIET, WITH ISOLATED PERIODS OF UNSETTLED
CONDITIONS, FOR THE NEXT THREE DAYS.
