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 010 Issued at 2200Z on 10 JAN 2000

IA. Analysis of Solar Active Regions and Activity from 09-2100Z to 10-2100Z

SOLAR ACTIVITY WAS MODERATE. REGION 8824 (S13E62) PRODUCED AN M3/2N EVENT AT 1350Z, NOT LONG AFTER IT HAD GENERATED A C9/SF AT 0912Z. THE GROUP IS A MODEST-SIZED BIPOLE, WITH A SEEMINGLY SIMPLE MAGNETIC STRUCTURE. NEWLY ASSIGNED REGION 8825 (N11E58) ROTATED INTO VIEW.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE LOW TO MODERATE.
IIA. Geophysical Activity Summary 09-2100Z to 10-2100Z
THE GEOMAGNETIC FIELD WAS QUIET. A SLIGHT ENHANCEMENT IN THE GREATER THAN 10 MEV PROTON FLUX AT GEOSYNCHRONOUS ORBIT BEGAN NEAR MIDDAY ON 09 JANUARY. THE FLUX ATTAINED A VALUE NEAR 2 PFU EARLY TODAY, AND IS NOW SUBSIDING. THE ENERGETIC ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT REACHED HIGH LEVELS AGAIN TODAY.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS EXPECTED TO BE PRIMARILY UNSETTLED FOR THE NEXT 24 HOURS. THE EFFECTS OF A HIGH-SPEED SOLAR WIND STREAM MAY RESULT IN OCCASIONAL ACTIVE CONDITIONS. THIS DISTURBANCE SHOULD FADE QUICKLY, GIVING WAY TO QUIET CONDITIONS BY THE END OF THE PERIOD.
