Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 96 Issued at 2200Z on 06 Apr 2014
IA. Analysis of Solar Active Regions and Activity from 05/2100Z to
06/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C3 event observed at
06/2101Z from Region 2031 (N03W25). 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 and two (07 Apr, 08 Apr) and
expected to be low with a slight chance for an M-class flare on day
three (09 Apr).
IIA. Geophysical Activity Summary 05/2100Z to 06/2100Z: 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
488 km/s at 05/2219Z. Total IMF reached 17 nT at 06/0212Z. The maximum
southward component of Bz reached -4 nT at 06/1121Z.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one and two (07 Apr, 08 Apr) and quiet to
unsettled levels on day three (09 Apr).
