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 360 Issued at 2200Z on 26 Dec 2006

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

Solar activity was very low. No new regions were numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be very low.
IIA. Geophysical Activity Summary 25-2100Z to 26-2100Z
The geomagnetic field was at quiet levels. The greater than 2 MeV electron flux at geosynchronous orbit was at high levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be quiet to unsettled with isolated active conditions for 27 December due to a recurrent solar sector boundary crossing. Predominately quiet conditions are expected for 28-29 December.
