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 279 Issued at 2200Z on 06 OCT 1997IA. Analysis of Solar Active Regions and Activity from 05-2100Z to 06-2100Z SOLAR ACTIVITY HAS BEEN VERY LOW WITH JUST MINOR
ISOLATED LOW FREQUENCY SWEEPS AND BURSTS.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO REMAIN
VERY LOW FOR THE ENTIRE PERIOD.
IIA. Geophysical Activity Summary 05-2100Z to 06-2100Z
THE GEOMAGNETIC FIELD WAS QUIET AT ALL LATITUDES.
IIB. Geophysical Activity Forecast
THE GEOPHYSICAL FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED FOR THE ENTIRE PERIOD DUE TO
FAVORABLE POSITIONING OF AN EXTENSION OF THE NORTHERN POLAR CORONAL
HOLE.
