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 015 Issued at 2200Z on 15 JAN 2000

IA. Analysis of Solar Active Regions and Activity from 14-2100Z to 15-2100Z

SOLAR ACTIVITY WAS LOW. SEVERAL MINOR C-CLASS X-RAY EVENTS WERE OBSERVED. REGION 8827 (S12W70) PRODUCED MOST OF THE ACTIVITY DURING THE PERIOD. REGION 8824 (S14W03) REMAINS THE MOST COMPLEX REGION ON THE DISK WITH A BETA-GAMMA MAGNETIC CONFIGURATION AND APPROXIMATELY 70 SUNSPOTS. NEW REGIONS 8834 (S16W60), AND 8835 (N08E57) WERE NUMBERED TODAY.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE LOW TO MODERATE. REGION 8824 HAS THE BEST POTENTIAL TO PRODUCED AN M-CLASS EVENT.
IIA. Geophysical Activity Summary 14-2100Z to 15-2100Z
THE GEOMAGNETIC FIELD WAS QUIET. THE GREATER THAN 2 MEV ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT WAS ENHANCED BUT STARTED TO DECREASE NEAR THE END OF THE PERIOD.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS EXPECTED TO REMAIN QUIET.
