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 361 Issued at 2200Z on 26 Dec 2000

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

Solar activity has been moderate. Two new regions were numbered today: 9288 (S21E26) and 9289 (S07E81). The latter produced an M1/SF east limb event at 26/1613 UTC. Other activity included several instances of low- and mid-level C-class activity, most of which was optically uncorrelated, but with Region 9283 (S11E24) indicated by SOHO/EIT data as a likely source for some of this activity. An active prominence on the southeast limb (S30E90) was observed late in the period.
IB. Solar Activity Forecast
Solar activity is expected to be low to moderate. Regions 9280 (N09W18), 9283, and 9289 all have potential for isolated M-class activity.
IIA. Geophysical Activity Summary 25-2100Z to 26-2100Z
The geomagnetic filed was quiet throughout the period.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be quiet to unsettled for the next three days.
