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 017 Issued at 2200Z on 17 JAN 1997

IA. Analysis of Solar Active Regions and Activity from 16-2100Z to 17-2100Z

SOALR ACTIVITY WAS VERY LOW. THERE WAS NO SIGNIFICANT ACTIVITY NOTED. REGION 8011 (S06W04) IS THE ONLY SPOTTED REGION ON THE VISIBLE DISK. IT IS A SIMPLE AXX SPOT GROUP AND SLOWLY DECAYING. THE REMAINDER OF THE VISIBLE DISK REMAINS QUIET AND STABLE.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE VERY LOW FOR THE ENTIRE FORECAST PERIOD.
IIA. Geophysical Activity Summary 16-2100Z to 17-2100Z
THE GEOMAGNETIC FIELD HAS BEEN QUIET AT ALL LATITUDES. THE GREATER THAN 2 MEV ENERGETIC ELECTRON FLUX RANGED FROM MODERATE TO HIGH LEVELS OVER THE PAST 24 HOURS.
