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 220 Issued at 2200Z on 07 AUG 2000IA. Analysis of Solar Active Regions and Activity from 06-2100Z to 07-2100Z SOLAR ACTIVITY WAS LOW. ONLY A FEW SMALL C-CLASS FLARES
OCCURRED, NONE OF WHICH WERE ASSOCIATED WITH REPORTED OPTICAL
FLARES. REGION 9114 (N12E14) CONTINUED TO PRODUCE SMALL SUBFLARES.
THIS REGION HAS DECLINED SOMEWHAT IN SUNSPOT AREA AND COMPLEXITY.
NEW REGION 9122 (N21E47) IS EMERGING RAPIDLY.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE LOW.
ADDITIONAL SMALL C-CLASS FLARES ARE EXPECTED.
IIA. GEOPHYSICAL ACTIVITY SUMMARY 06/2100Z TO 07/2100Z:
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED. THE GREATER THAN 2 MEV
ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT WAS MODERATE.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED FOR THE ENTIRE FORECAST PERIOD.
