SDF Number 158 Issued at 2200Z on 06 Jun 2016

IA.  Analysis of Solar Active Regions and Activity from 05/2100Z to
06/2100Z: 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 (07
Jun, 08 Jun, 09 Jun).

IIA.  Geophysical Activity Summary 05/2100Z to 06/2100Z: The geomagnetic
field has been at quiet to major storm levels for the past 24 hours.
Solar wind speed reached a peak of 694 km/s at 06/0322Z. Total IMF
reached 9 nT at 06/0007Z. The maximum southward component of Bz reached
-8 nT at 06/0006Z. Electrons greater than 2 MeV at geosynchronous orbit
reached a peak level of 801 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (07 Jun) and quiet levels
on days two and three (08 Jun, 09 Jun).
