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 067 Issued at 2200Z on 07 MAR 2000IA. Analysis of Solar Active Regions and Activity from 06-2100Z to 07-2100Z SOLAR ACTIVITY INCREASED TO MODERATE LEVELS. AN M1/1F
FLARE OCCURRED AT 07/1607UT FROM AN AS YET UNNUMBERED REGION
ROTATING INTO VIEW NEAR SE22. AN OPTICALLY UNCORRELATED M1 OCCURRED
AT 07/1950UT. MINOR SPOT DEVELOPMENT WAS REPORTED WITHIN REGION 8900
(S16W26), WHICH CONTINUED TO DISPLAY A MIXED-POLARITY STRUCTURE.
HOWEVER, THE REGION WAS STABLE DURING MOST OF THE PERIOD. THE
REMAINING REGIONS WERE STABLE. NEW REGION 8903 WAS ASSIGNED.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE. ISOLATED LOW-LEVEL M-CLASS FLARES ARE POSSIBLE.
IIA. Geophysical Activity Summary 06-2100Z to 07-2100Z
FIELD ACTIVITY RANGED FROM UNSETTLED TO ACTIVE LEVELS.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE AT MOSTLY QUIET TO UNSETTLED LEVELS. HOWEVER, BRIEF
ACTIVE PERIODS ARE ALSO POSSIBLE DURING THE PERIOD.
