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 270 Issued at 2200Z on 26 SEP 1996

IA. Analysis of Solar Active Regions and Activity from 25-2100Z to 26-2100Z

SOLAR ACTIVITY WAS VERY LOW. THE DISK REMAINS SPOTLESS.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE VERY LOW.
IIA. Geophysical Activity Summary 25-2100Z to 26-2100Z
THE GEOMAGNETIC FIELD WAS AT QUIET TO MINOR STORM LEVELS. A HIGH SPEED STREAM BEGAN TO HAVE AN EFFECT AROUND MIDDAY AND CONTINUES. THE GREATER THAN 2 MEV ELECTRON FLUX WAS HIGH.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS EXPECTED TO BE GENERALLY ACTIVE OVER THE NEXT 24 HOURS DUE TO CORONAL HOLE EFFECTS. QUIET TO UNSETTLED CONDITIONS ARE LIKELY BY THE END OF THE PERIOD.
