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 008 Issued at 2200Z on 08 Jan 2001

IA. Analysis of Solar Active Regions and Activity from 07-2100Z to 08-2100Z

Solar activity was low. Occasional C-class x-ray events occurred, the largest a C5 at 1105 UTC. Region 9302 (N18E25) is the probable source of that flare, as inferred from YOHKOH/SXT data. One new region was numbered, 9306 (N12E58), a mature bipole with twelve spots. There may be other regions soon to appear at east limb, as indicated by surging near NE12.
IB. Solar Activity Forecast
Solar activity is expected to persist at the low level.
IIA. Geophysical Activity Summary 07-2100Z to 08-2100Z
