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 2012IA. Analysis of Solar Active Regions and Activity from 13-2100Z to 14-2100Z Solar activity has been at moderate levels for the past
24 hours. An M1 x-ray flare was observed at 14/1318Z from new
sunspot Region 1401 (N15E73). Three other new regions were numbered
in the past 24 hours, Region 1399 (S24E69), Region 1400 (S14W04),
and Region 1402 (N26E75). Even though Region 1401 and 1402 have just
rotated onto the visible disk, imagery and data from the STEREO B
spacecraft has shown these regions are active.
IB. Solar Activity Forecast
Solar activity is expected to be at
low levels with a chance for more M-class events for the next three
days (15 - 17 January), as Regions 1401 and 1402 continue to rotate
onto the disk.
IIA. Geophysical Activity Summary 13-2100Z to 14-2100Z
The geomagnetic field has been at quiet levels for the past 24 hours.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to remain at mostly quiet levels for the next two days (15
- 16 January). An increase to quiet to unsettled levels is expected
on day three (17 January) as a coronal hole high speed stream
becomes geoeffective.
