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
: : : : : CORRECTED COPY : : : : : : : : : : SDF Number 306 Issued at 2200Z on 02 NOV 1998IA. Analysis of Solar Active Regions and Activity from 01-2100Z to 02-2100Z SOLAR ACTIVITY WAS LOW. A SINGLE C4/1F EVENT OCCURRED
IN REGION 8376 (S27E41) AT 02/1358UT. THIS IS A NEW NUMBERED REGION
DUE TO THE FACT THAT IT CREATED AN X-RAY AND OPTICAL FLARE, EVEN
THOUGH IT DOES NOT CONTAIN ANY SPOTS. ANOTHER NEW REGION WAS
NUMBERED 8377 (N22E75). REGION 8377 IS ROTATING ONTO THE EAST LIMB
AND CONTAINS A SINGLE SPOT AT THIS TIME. REGION 8375 (N19E20)
PRODUCED A SINGLE OPTICAL FLARE. THE REST OF THE REGIONS HAVE BEEN
MOSTLY QUIET AND STABLE.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE VERY
LOW TO LOW. ISOLATED C-CLASS FLARES MAY OCCUR FROM REGIONS 8375 AND
8376.
IIA. Geophysical Activity Summary 01-2100Z to 02-2100Z
THE GEOMAGNETIC FIELD WAS QUIET. ENERGETIC ELECTRONS AT
GEOSYNCHRONOUS ORBIT WERE AT HIGH LEVELS FOR MOST OF THE PERIOD AND
THEN FALLING BELOW THRESHOLD LEVELS AT 02/2000UT.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED.
