Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 102 Issued at 2200Z on 11 Apr 2012
IA.  Analysis of Solar Active Regions and Activity from  10/2100Z
to 11/2100Z:  Solar activity has been at very low levels for the past
24 hours. An emerging flux region was numbered today as Region 1455
(N07E08) and was magnetically classified as a beta group.
IB.  Solar Activity Forecast:  Solar activity is expected to be at
very low levels with a slight chance for C-class events for the next
three days (12-14 April).
IIA.  Geophysical Activity Summary 10/2100Z to 11/2100Z:
The geomagnetic field has been at predominantly quiet levels for the
past 24 hours.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be at quiet to unsettled levels with a slight chance for
active conditions for the next three days (12-14 April) as a coronal
hole high speed stream becomes geoeffective.
