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 280 Issued at 2200Z on 07 OCT 1997

IA. Analysis of Solar Active Regions and Activity from 06-2100Z to 07-2100Z

SOLAR ACTIVITY HAS BEEN VERY LOW WITH MINOR ISOLATED LOW FREQUENCY SWEEPS AND BURSTS. A SPACE BASED SENSOR DETECTED A CORONAL MASS EJECTION OFF THE SE LIMB AT 06/1600Z WHICH MAY HAVE BEEN COINCIDENT WITH A LARGE DSF REPORTED AT 06/2230Z. A SECOND CORONAL MASS EJECTION WAS OBSERVED OFF THE WEST LIMB AT 07/1330Z BUT NO OPTICAL ACTIVITY WAS OBSERVED AT THAT TIME.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO REMAIN VERY LOW TO LOW.
IIA. Geophysical Activity Summary 06-2100Z to 07-2100Z
THE GEOMAGNETIC WAS QUIET AT ALL LEVELS.
IIB. Geophysical Activity Forecast
THE GEOPHYSICAL FIELD IS EXPECTED TO REMAIN QUIET.
