Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 233 Issued at 2200Z on 21 Aug 2014
IA. Analysis of Solar Active Regions and Activity from 20/2100Z to
21/2100Z: Solar activity has been at moderate levels for the past 24
hours. The largest solar event of the period was a M3 event observed at
21/1331Z from Region 2149 (N12E77). 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 (22 Aug, 23 Aug,
24 Aug).
IIA. Geophysical Activity Summary 20/2100Z to 21/2100Z: 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
356 km/s at 21/2015Z. Total IMF reached 13 nT at 20/2102Z. The maximum
southward component of Bz reached -7 nT at 21/0520Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 522 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (22 Aug) and quiet levels on
days two and three (23 Aug, 24 Aug).
