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 015 Issued at 2200Z on 15 Jan 2006IA. Analysis of Solar Active Regions and Activity from 14-2100Z to 15-2100Z Solar activity has been low. Two new regions were
numbered today; Region 847 (S09W08) which produced a C1 flare at
15/1445Z and Region 846 (N05W30) which has developed from a plage
region into a Dso Beta group.
IB. Solar Activity Forecast
Solar activity is expected to be very
low to low.
IIA. Geophysical Activity Summary 14-2100Z to 15-2100Z
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be mostly unsettled with a chance for active periods on
16 January due to a geoeffective coronal hole high speed stream.
Quiet to unsettled conditions are expected on 17 - 18 January.
