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 330 Issued at 2200Z on 26 Nov 2005IA. Analysis of Solar Active Regions and Activity from 25-2100Z to 26-2100Z Solar activity was low. A C1.0 flare occurred from
Region 822 at 26/0409 UTC on the west limb at approximately S09.
IB. Solar Activity Forecast
Solar activity is expected to be very
low with a slight chance for a C-flare.
IIA. Geophysical Activity Summary 25-2100Z to 26-2100Z
The geomagnetic field was mostly quiet. The greater than 2 MeV
electron flux at geosynchronous orbit was at high levels again
today.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled. On 28 and 29 November, isolated
active periods are possible.
