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.

SDF Number 268 Issued at 2200Z on 24 SEP 1996

IA. Analysis of Solar Active Regions and Activity from 23-2100Z to 24-2100Z

SOLAR ACTIVITY WAS VERY LOW. THE DISK IS SPOTLESS.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE VERY LOW.
IIA. Geophysical Activity Summary 23-2100Z to 24-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED AS THE HIGH SOLAR WIND SPEEDS HAVE ABATED IN THE PAST 24 HOURS. THE GREATER THAN 2 MEV ELECTRON FLUX WAS HIGH.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS EXPECTED TO BE AT ACTIVE TO MINOR STORM LEVELS DURING THE NEXT 24-36 HOURS AS ANOTHER HIGH SPEED STREAM IS ANTICIPATED. THIS RECURRENT DISTURBANCE SHOULD END BY 27 SEPTEMBER.
