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 184 Issued at 2200Z on 02 JUL 2000

IA. Analysis of Solar Active Regions and Activity from 01-2100Z to 02-2100Z

SOLAR ACTIVITY WAS MODERATE BY VIRTUE OF AN M1 FLARE AT 01/2325 UTC. NO OPTICAL FLARE REPORTS WERE RECEIVED AND IMAGES FROM THE SOHO SPACECRAFT SUGGEST THAT THE SOURCE OF THE FLARE WAS NOT ON THE VISIBLE SOLAR HEMISPHERE. REGION 9062 (S16W18) CONTINUES TO DECAY AND SIMPLIFY BUT REMAINS THE LARGEST SUNSPOT GROUP ON THE DISK. REGION 9068 (S19E51) IS EMERGING RAPIDLY AND HAS PRODUCED SEVERAL SMALL C-CLASS SUBFLARES. NEW REGION 9070 (N19E72) ROTATED ONTO THE VISIBLE DISK.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE LOW TO MODERATE. C-CLASS ACTIVITY IS EXPECTED TO CONTINUE IN REGION 9068. ANOTHER LOW-LEVEL M-CLASS FLARE IS POSSIBLE.
IIA. Geophysical Activity Summary 01-2100Z to 02-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS EXPECTED TO BE QUIET TO UNSETTLED.
