Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 260 Issued at 2200Z on 17 Sep 2014


IA.  Analysis of Solar Active Regions and Activity from 16/2100Z to
17/2100Z: 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
17/1948Z from Region 2158 (N15W93). 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 day one (18 Sep) and likely to be low
with a slight chance for an M-class flare on days two and three (19 Sep,
20 Sep).


IIA.  Geophysical Activity Summary 16/2100Z to 17/2100Z: 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
416 km/s at 16/2120Z. Total IMF reached 8 nT at 17/2058Z. The maximum
southward component of Bz reached -5 nT at 16/2240Z.

IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (18 Sep, 19 Sep, 20
Sep).
