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 006 Issued at 2200Z on 06 Jan 2001

IA. Analysis of Solar Active Regions and Activity from 05-2100Z to 06-2100Z

Solar activity was low. A C3 x-ray event at 1520 UTC, when both Regions 9302 (N19E52) and 9291 (S13W76) had Sf optical flares, was the premier flare event of the period. Little else of significance occurred, although another new region, 9303 (S04W47) emerged. Currently there are twelve assigned regions visible, with the possibility of more to come. There are reports of additional groups coming fully into view at east limb.
IB. Solar Activity Forecast
Solar activity is expected to be low to moderate. Regions 9302 and 9289 (S05W67) have potential for M-class flares.
IIA. Geophysical Activity Summary 05-2100Z to 06-2100Z
The geomagnetic field was quiet to unsettled. There was an enhancement in the greater than 10 MeV protons at geosynchronous orbit that began late on 05 January. These particles may be an effect of a large halo CME directed away from earth seen by LASCO at 1706 UTC yesterday.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be unsettled through 09 January.
