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 026 Issued at 2200Z on 26 Jan 2001

IA. Analysis of Solar Active Regions and Activity from 25-2100Z to 26-2100Z

Solar activity reached moderate levels. Region 9325 (N10E50) produced an M1/1b flare at 26/0607 UTC associated with a Type II radio sweep. This region was simply structured and showed no significant changes during the period. Region 9313 (S07W40) produced isolated B- and C-class subflares and showed no significant changes in size or structure. Region 9320 (S25W61), a small A-type group, produced a C1/Sf flare at 26/1206 UTC associated with a Type II radio sweep, but was otherwise stable. New Region 9326 (N27W27) was numbered.
IB. Solar Activity Forecast
Solar activity is expected to be low. However, there will be a fair chance for an isolated M-class flare sometime during the period.
IIA. Geophysical Activity Summary 25-2100Z to 26-2100Z
Geomagnetic field activity was at quiet levels during most of the period. However, an isolated active period occurred during 26/0700 - 0900 UTC.
IIB. Geophysical Activity Forecast
Geomagnetic field activity is expected to remain at mostly quiet levels.
