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 090 Issued at 2200Z on 30 MAR 2000

IA. Analysis of Solar Active Regions and Activity from 29-2100Z to 30-2100Z

SOLAR ACTIVITY WAS MODERATE. REGION 8936 (S16E58) PRODUCED AN IMPULSIVE M3/1N EVENT AT 30/1607Z. THE TOTAL DURATION OF THE M3 EVENT WAS ONLY 14 MINUTES. REGION 8936 ALSO PRODUCED AN M1/SF EVENT EARLIER AT 30/1245Z. AN OPTICALLY UNCORRELATED M1 X-RAY EVENT OCCURRED AT 30/0714Z. SEVERAL OTHER MINOR C-CLASS EVENTS OCCURRED DURING THE PERIOD FROM REGION 8936 AND 8925 (S18W20). REGION 8924 (N10W28) AND 8925 EACH BECAME MORE MAGNETICALLY COMPLEX WITH A BETA-GAMMA MAGNETIC CONFIGURATION. FURTHER GROWTH WAS OBSERVED IN REGION 8936. FOUR NEW REGIONS, 8938 (S07E56), 8939 (N22E72), 8940 (N13E65), AND 8941 (N25E54) WERE NUMBERED TODAY.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE MODERATE.
IIA. Geophysical Activity Summary 29-2100Z to 30-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO ACTIVE.
IIB. Geophysical Activity Forecast
