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 014 Issued at 2200Z on 14 Jan 2011IA. Analysis of Solar Active Regions and Activity from 13-2100Z to 14-2100Z Solar activity was low. Old region 1138 (N12, L=323),
which has yet to rotate onto the visible disk, produced a long
duration C1 x-ray event at 14/0330Z associated with a CME off the
northeast limb. Region 1145 (N16W25) redeveloped spots.
IB. Solar Activity Forecast
Solar activity is expected to be very
low to low for the next three days (15 - 17 January).
IIA. Geophysical Activity Summary 13-2100Z to 14-2100Z
Geomagnetic field activity was mostly quiet. An isolated unsettled
period was observed at mid-latitudes between 14/1500 - 1800Z.
IIB. Geophysical Activity Forecast
Geomagnetic field activity is
expected to be at quiet to unsettled levels on day one (15 January)
as the effects of a recurrent coronal hole high speed stream (CH
HSS) become geoeffective. Quiet levels are expected on days two and
three (16 -17 January) as effects from the CH HSS wane.
