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 011 Issued at 2200Z on 11 Jan 2012IA. Analysis of Solar Active Regions and Activity from 10-2100Z to 11-2100Z Solar activity was low. Nominal C-class flares
occurred.
IB. Solar Activity Forecast
Solar activity is expected to be very
low to low with a chance for a M-class flare for the next 3 days
(12-14 January).
IIA. Geophysical Activity Summary 10-2100Z to 11-2100Z
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is
forecast to be mostly quiet on day 1 (12 January). Conditions are
expected to increase for days 2-3 (13-14 January), with possible
unsettled and active conditions due to a high speed stream (HSS)
from a coronal hole (CH).
