Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 104 Issued at 2200Z on 14 Apr 2014

IA.  Analysis of Solar Active Regions and Activity from 13/2100Z to
14/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C7 event observed at
14/0438Z from Region 2036 (S18E13). There are currently 6 numbered
sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is expected to be low with
a chance for M-class flares on days one, two, and three (15 Apr, 16 Apr,
17 Apr).

IIA.  Geophysical Activity Summary 13/2100Z to 14/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
408 km/s at 14/0542Z. Total IMF reached 6 nT at 13/2255Z. The maximum
southward component of Bz reached -5 nT at 14/1732Z.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (15 Apr) and quiet levels
on days two and three (16 Apr, 17 Apr).
