Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 240 Issued at 2200Z on 28 Aug 2014


IA.  Analysis of Solar Active Regions and Activity from 27/2100Z to
28/2100Z: 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
28/1520Z from Region 2146 (N08W86). There are currently 6 numbered
sunspot regions on the disk.

IB.  Solar Activity Forecast: Solar activity is expected to be low with
a slight chance for an M-class flare on days one and two (29 Aug, 30
Aug) and likely to be low with a slight chance for an M-class flare on
day three (31 Aug).


IIA.  Geophysical Activity Summary 27/2100Z to 28/2100Z: The geomagnetic
field has been at unsettled to minor storm levels for the past 24 hours.
Solar wind speed, as measured by the ACE spacecraft, reached a peak
speed of 386 km/s at 28/1026Z. Total IMF reached 13 nT at 27/2100Z. The
maximum southward component of Bz reached -11 nT at 28/0244Z. Electrons
greater than 2 MeV at geosynchronous orbit reached a peak level of 280
pfu.

IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (29 Aug) and quiet to
unsettled levels on days two and three (30 Aug, 31 Aug). Protons greater
than 10 Mev have a slight chance of crossing threshold on days one and
two (29 Aug, 30 Aug).
