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 2000IA. 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

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.
