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 024 Issued at 2200Z on 24 Jan 2005

IA. Analysis of Solar Active Regions and Activity from 23-2100Z to 24-2100Z

Solar activity decreased to very low levels today. All three spotted active regions were responsible for the low level B-class flare activity reported throughout the period. Region 727 (S09E38) was numbered today and is undergoing rapid growth in penumbral coverage.
IB. Solar Activity Forecast
Solar activity is expected to be at very low to low levels. Continued growth in Region 727 may lead to C-class flare activity.
IIA. Geophysical Activity Summary 23-2100Z to 24-2100Z
The geomagnetic field was at predominantly quiet levels. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels today.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to unsettled levels throughout the period.
