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 185 Issued at 2200Z on 03 JUL 2000

IA. Analysis of Solar Active Regions and Activity from 02-2100Z to 03-2100Z

SOLAR ACTIVITY WAS VERY LOW. ONLY A FEW SUBFLARES OCCURRED, ALL OF WHICH WERE LESS THAN C-CLASS. GROWTH IN REGION 9068 (S19E38) HAS SLOWED. ALL SUNSPOT GROUPS PRESENTLY ON THE DISK ARE RELATIVELY SIMPLE AND INACTIVE.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE LOW. LOW-LEVEL C-CLASS FLARES ARE POSSIBLE IN A NUMBER OF REGIONS WITH 9068 BEING THE MOST LIKELY.
IIA. Geophysical Activity Summary 02-2100Z to 03-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS EXPECTED TO BE QUIET TO UNSETTLED BECOMING UNSETTLED TO ACTIVE BY THE END OF THE FORECAST PERIOD DUE TO A FAVORABLY POSITIONED CORONAL HOLE.
