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 076 Issued at 2200Z on 16 MAR 2000

IA. Analysis of Solar Active Regions and Activity from 15-2100Z to 16-2100Z

SOLAR ACTIVITY WAS LOW. THE LARGEST FLARE WAS A C9/1F AT 16/1838UT IN REGION 8906 (S16W37). THIS REGION HAS DECAYED FURTHER SINCE YESTERDAY ALTHOUGH IT STILL RETAINS SOME MAGNETIC COMPLEXITY. REGION 8910 (N11E18) CONTINUES TO DEVELOP AND MANAGED TO GENERATE A C6/SF FLARE AT 18/1420UT.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE LOW TO MODERATE. REGION 8906 REMAINS THE MOST LIKELY SOURCE OF M-CLASS ACTIVITY. THERE IS STILL A CHANCE OF A MAJOR FLARE IN THIS REGION. C-CLASS FLARES AND ISOLATED M-CLASS ACTIVITY IS POSSIBLE IN REGION 8910.
IIA. Geophysical Activity Summary 15-2100Z to 16-2100Z
THE GEOMAGNETIC FIELD WAS QUIET.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS EXPECTED TO BE QUIET TO UNSETTLED.
