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 043 Issued at 2200Z on 12 FEB 1997IA. Analysis of Solar Active Regions and Activity from 11-2100Z to 12-2100Z
SOLAR ACTIVITY REMAINED VERY LOW. THE DISK CONTINUED
SPOTLESS.
IB. Solar Activity Forecast
SOLAR ACTIVITY SHOULD REMAIN AT VERY
LOW LEVELS FOR THE NEXT THREE DAYS.
IIA. Geophysical Activity Summary 11-2100Z to 12-2100Z
THE GEOMAGNETIC FIELD WAS UNSETTLED TO SLIGHTLY ACTIVE FOR THE FIRST
HALF OF THE PERIOD AND QUIET FOR THE LATTER HALF. SOLAR WIND DATA
SHOW A BENIGN FLOW IN THE EARTH'S VICINITY NOW THAT THE MAGNETIC
CLOUD/CME PASSED BY THE EARTH. ENERGETIC ELECTRON FLUXES AT
GEOSYNCHRONOUS ORBIT WERE HIGH.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS
FORECAST TO BE PREDOMINANTLY QUIET FOR THE NEXT THREE DAYS.
