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 183 Issued at 2200Z on 01 JUL 2000

IA. Analysis of Solar Active Regions and Activity from 30-2100Z to 01-2100Z

SOLAR ACTIVITY WAS LOW. THE LARGEST FLARE OF THE PAST DAY WAS A C6/SF AT 01/1241 UTC IN REGION 9054 (N13W81). THIS SUNSPOT GROUP CONTINUES TO DECAY AS IT APPROACHES THE WEST LIMB. REGION 9062 (S16W04) IS THE LARGEST GROUP ON THE VISIBLE DISK BUT IS NOT PARTICULARLY COMPLEX AND HAS NOT PRODUCED SIGNIFICANT ACTIVITY. NEW REGIONS 9068 (S19E63) AND 9069 (S13E70) ROTATED INTO VIEW.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE LOW. ADDITIONAL C-CLASS FLARES ARE POSSIBLE FROM REGION 9054 BEFORE IT EXITS THE VISIBLE DISK. THERE IS A SMALL CHANCE OF LOW-LEVEL M-CLASS ACTIVITY.
IIA. Geophysical Activity Summary 30-2100Z to 01-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS EXPECTED TO BE QUIET TO UNSETTLED.
