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 161 Issued at 2200Z on 10 JUN 1997IA. Analysis of Solar Active Regions and Activity from 09-2100Z to 10-2100Z SOLAR ACTIVITY REMAINED VERY LOW. ONLY ONE SMALL REGION
WITH A SINGLE SPOT WAS OBSERVED. A LATE REPORT WAS RECEIVED FROM THE
MAUNA LOA CORONAGRAPH REGARDING AN ERUPTIVE PROMINENCE AT NW30-45
FROM 09/2000-2030Z. THIS EVENT WAS ACCOMPANIED BY A MODERATE
DURATION B2 X-RAY ENHANCEMENT. A CORONAL MASS EJECTION WAS PROBABLE
WITH THIS EVENT.
IB. Solar Activity Forecast
SOLAR ACTIVITY SHOULD REMAIN AT A VERY
LOW LEVEL FOR THE NEXT THREE DAYS.
IIA. Geophysical Activity Summary 09-2100Z to 10-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO SLIGHTLY UNSETTLED. ENERGETIC
ELECTRON FLUXES AT GEOSYNCHRONOUS ORBIT WERE BELOW EVENT THRESHOLD.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO SLIGHTLY UNSETTLED FOR THE NEXT THREE DAYS.
THE EPL/CME MENTIONED ABOVE IS NOT EXPECTED TO IMPACT THE EARTH.
