Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 160 Issued at 2200Z on 09 Jun 2017

IA.  Analysis of Solar Active Regions and Activity from 08/2100Z to
09/2100Z: 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
with a slight chance for a C-class flare on days one, two, and three (10
Jun, 11 Jun, 12 Jun).

IIA.  Geophysical Activity Summary 08/2100Z to 09/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 337 km/s at 09/0220Z. Total IMF reached 6
nT at 08/2310Z. The maximum southward component of Bz reached -5 nT at
08/2240Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 361 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one and two (10 Jun, 11 Jun) and quiet to
unsettled levels on day three (12 Jun).
