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 334 Issued at 2200Z on 30 Nov 2005

IA. Analysis of Solar Active Regions and Activity from 29-2100Z to 30-2100Z

Solar activity increased to moderate levels today. Region 826 (S02E36) produced an impulsive M1 x-ray flare occurring at 30/1752Z. White-light observations in Region 826, depict a rapid growth phase in sunspot area since yesterday. This region has also developed in magnetic complexity, with beta-gamma characteristics evident. New Region 827 (N08E56) was numbered today and is currently a simply structured beta group.
IB. Solar Activity Forecast
Solar activity is expected to be at low to moderate levels. Region 826 is magnetically complex enough to produce further isolated M-class flares.
IIA. Geophysical Activity Summary 29-2100Z to 30-2100Z
The geomagnetic field was at predominantly quiet to unsettled levels. A period of active conditions occurred at middle and high latitudes between 30/0900 and 1200Z
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at predominantly unsettled to active levels. Minor storm conditions with a chance of high latitude major storm periods are possible on 01 and 02 December due to a recurrent high speed coronal hole stream. A return to predominantly quiet to unsettled levels is expected on 03 December as the coronal moves out of geoeffective position.
