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 306 Issued at 2200Z on 02 NOV 1997

IA. Analysis of Solar Active Regions and Activity from 01-2100Z to 02-2100Z

SOLAR ACTIVITY BECAME LOW. REGION 8100 (S19W11) PRODUCED A C2/SB FLARE AT 02/0304Z WITH MINOR RADIO BURSTS AND A C2/SF AT 02/2049Z. REGION 8100 ALSO PRODUCED SEVERAL B-CLASS SUBFLARES. GROWTH BEGAN ANEW IN THIS REGION LATE ON 01 NOV. SEVERAL SMALL ISLANDS OF OPPOSITE POLARITY EMERGED THROUGHOUT THE REGION COMPLICATING THE EXISTING BETA GAMMA MAGNETIC CLASSIFICATION. A SMALL REGION EMERGED NEAR N30E13 AND WAS NUMBERED AS NEW REGION 8102.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE PREDOMINANTLY LOW. REGION 8100 SHOULD CONTINUE TO PRODUCE IMPULSIVE SMALL AREA C-CLASS EVENTS NEAR THE SMALL REGIONS OF EMERGING FLUX. OCCASIONAL SMALL M-CLASS EVENTS ARE POSSIBLE - ESPECIALLY IF GROWTH AND INCREASE IN MAGNETIC COMPLEXITY IN THE REGION CONTINUE.
IIA. Geophysical Activity Summary 01-2100Z to 02-2100Z
THE GEOMAGNETIC FIELD WAS QUIET. RECENT SOLAR WIND DATA INDICATE A BENIGN SLOW SPEED FLOW IN THE EARTH'S VICINITY. ENERGETIC ELECTRON FLUXES AT GEOSYNCHRONOUS ORBIT AGAIN REACHED HIGH LEVELS DURING THE PERIOD.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS EXPECTED TO BE QUIET TO UNSETTLED FOR 03-04 NOV. MOSTLY UNSETTLED CONDITIONS ARE PREDICTED ON 06 NOV.
