Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 289 Issued at 2200Z on 16 Oct 2014

IA.  Analysis of Solar Active Regions and Activity from 15/2100Z to
16/2100Z: Solar activity has been at moderate levels for the past 24
hours. The largest solar event of the period was a M4 event observed at
16/1303Z. There are currently 5 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 (17 Oct, 18 Oct,
19 Oct).

IIA.  Geophysical Activity Summary 15/2100Z to 16/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed,
as measured by the ACE spacecraft, reached a peak speed of 492 km/s at
16/1500Z. Total IMF reached 7 nT at 16/0313Z. The maximum southward
component of Bz reached -5 nT at 16/2013Z.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (17 Oct, 18 Oct)
and quiet levels on day three (19 Oct).
