Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 015 Issued at 2200Z on 15 Jan 2012
IA.  Analysis of Solar Active Regions and Activity from  14/2100Z
to 15/2100Z:  Solar activity has been at low levels for the past 24
hours. Region 1401 (N17E60) has been the most productive region,
producing multiple C-class events.  The largest event of the period
was C2 x-ray flare from around the west limb near old Region 1391
(N12, L=013). There are currently 9 numbered sunspot regions on the
disk, with Region 1403 (S19E29) being numbered today.
IB.  Solar Activity Forecast:  Solar activity is expected to be at
low levels with a slight chance for M-class flares for the next
three days (16 - 18 January).
IIA.  Geophysical Activity Summary 14/2100Z to 15/2100Z:
The geomagnetic field has been at quiet levels for the past 24 hours.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be at quiet levels on day one (16 January) and increase
to quiet to unsettled levels on days two and three (17 -18 January)
as a coronal hole high speed stream becomes geoeffective.
