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 259 Issued at 2200Z on 15 SEP 1996

IA. Analysis of Solar Active Regions and Activity from 14-2100Z to 15-2100Z

SOLAR ACTIVITY WAS VERY LOW. NO FLARES OCCURRED AS THE VISIBLE DISK REMAINS SPOTLESS AND ESSENTIALLY FEATURELESS.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE VERY LOW.
IIA. Geophysical Activity Summary 14-2100Z to 15-2100Z
THE GEOMAGNETIC FIELD HAS BEEN AT MOSTLY QUIET TO UNSETTLED LEVELS FOR THE PAST 24 HOURS, WITH ISOLATED PERIODS OF ACTIVE CONDITIONS. THE GREATER THAN 2 MEV ELECTRONS REMAIN AT HIGH LEVELS.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS EXPECTED TO BE QUIET TO UNSETTLED FOR THE NEXT THREE DAYS, WITH THE CHANCE FOR CONTINUED ISOLATED PERIODS OF ACTIVE CONDITIONS.
