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 019 Issued at 2200Z on 19 Jan 2006IA. Analysis of Solar Active Regions and Activity from 18-2100Z to 19-2100Z Solar activity was very low. A large filament eruption
and associated CME was observed off the SE limb today at about
19/1300Z. The CME does not appear to be Earth directed. Region 848
(S19E24) continues in a slow growth phase, and was responsible for
some low B-class activity.
IB. Solar Activity Forecast
Solar activity is expected to be very
low to low. There is a chance for a C-class flare from Region 848.
IIA. Geophysical Activity Summary 18-2100Z to 19-2100Z
The geomagnetic field was quiet to unsettled.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to continue at quiet to unsettled levels.
