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 164 Issued at 2200Z on 13 JUN 1997IA. Analysis of Solar Active Regions and Activity from 12-2100Z to 13-2100Z SOLAR ACTIVITY REMAINED VERY LOW. REGION 8052 (N17E28)
CONTINUED TO EMERGE AT A SLOW PACE. SOME MINOR MIXED POLARITIES WERE
OBSERVED IN THIS REGION.
IB. Solar Activity Forecast
SOLAR ACTIVITY SHOULD REMAIN VERY LOW
FOR THE NEXT THREE DAYS. CONTINUED GROWTH AND MAGNETIC COMPLEXITY IN
REGION 8052 COULD RESULT IN AN ISOLATED C-CLASS EVENT FROM THIS
REGION.
IIA. Geophysical Activity Summary 12-2100Z to 13-2100Z
THE GEOMAGNETIC FIELD WAS QUIET. ENERGETIC ELECTRON FLUXES AT
GEOSYNCHRONOUS ORBIT AGAIN REACHED HIGH LEVELS.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS
FORECAST TO BE PREDOMINANTLY QUIET FOR THE NEXT THREE DAYS.
