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 157 Issued at 2200Z on 06 JUN 1997IA. Analysis of Solar Active Regions and Activity from 05-2100Z to 06-2100Z SOLAR ACTIVITY WAS VERY LOW. REGION 8048 (S28W37), A
DAO SPOT GROUP, IS BEGINNING TO SHOW SLOW DECAY. THE REMAINDER OF
THE VISIBLE DISK IS SPOTLESS AND STABLE.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO REMAIN
VERY LOW FOR THE ENTIRE FORECAST PERIOD. REGION 8048 HAS AN OUTSIDE
CHANCE OF ISOLATED C-CLASS ACTIVITY.
IIA. Geophysical Activity Summary 05-2100Z to 06-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED AT ALL LATITUDES.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS
EXPECTED TO REMAIN QUIET TO UNSETTLED FOR THE NEXT 12-18 HOURS, THEN
BE MOSTLY QUIET FOR THE REMAINDER OF THE FORECAST PERIOD.
