SDF Number 314 Issued at 2200Z on 10 Nov 2017

IA.  Analysis of Solar Active Regions and Activity from 09/2100Z to
10/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 0 numbered sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is expected to be very low
on days one, two, and three (11 Nov, 12 Nov, 13 Nov).

IIA.  Geophysical Activity Summary 09/2100Z to 10/2100Z: The geomagnetic
field has been at unsettled to active levels for the past 24 hours.
Solar wind speed reached a peak of 719 km/s at 10/1257Z. Total IMF
reached 8 nT at 10/0519Z. The maximum southward component of Bz reached
-6 nT at 10/0606Z. Electrons greater than 2 MeV at geosynchronous orbit
reached a peak level of 17453 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to minor storm levels on day one (11 Nov) and quiet to
unsettled levels on days two and three (12 Nov, 13 Nov).
