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 302 Issued at 2200Z on 29 OCT 1997

IA. Analysis of Solar Active Regions and Activity from 28-2100Z to 29-2100Z

SOLAR ACTIVITY WAS VERY LOW. BOTH SPOTTED REGIONS, 8099 (N20E11) AND 8100 (S21E44) WERE QUIET AND STABLE. NO SIGNIFICANT FLARE ACTIVITY OCCURRED.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE LOW. REGION 8100 IS LIKELY TO GENERATE OCCASIONAL C-CLASS ACTIVITY.
IIA. Geophysical Activity Summary 28-2100Z to 29-2100Z
THE GEOMAGNETIC FIELD WAS PREDOMINANTLY QUIET TO UNSETTLED. WEAK SUBSTORMS BROUGHT EPISODES OF ACTIVE CONDITIONS TO HIGH LATITUDES. THE GREATER THAN 2 MEV ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT ONCE AGAIN REACHED HIGH LEVELS DURING THE LATTER PART OF THE PERIOD.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS EXPECTED TO BE QUIET TO UNSETTLED FOR THE NEXT THREE DAYS.
