Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 95 Issued at 2200Z on 05 Apr 2014

IA.  Analysis of Solar Active Regions and Activity from 04/2100Z to
05/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C1 event observed at
05/1050Z from Region 2026 (S11W04). There are currently 7 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 (06 Apr, 07 Apr,
08 Apr).

IIA.  Geophysical Activity Summary 04/2100Z to 05/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
548 km/s at 05/1346Z. Total IMF reached 12 nT at 05/2036Z. The maximum
southward component of Bz reached -7 nT at 05/1102Z.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (06 Apr) and quiet levels
on days two and three (07 Apr, 08 Apr).
