Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 158 Issued at 2200Z on 07 Jun 2017

IA.  Analysis of Solar Active Regions and Activity from 06/2100Z to
07/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C1 event observed at
07/0333Z from Region 2661 (N07W11). There are currently 1 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 (08
Jun, 09 Jun, 10 Jun).

IIA.  Geophysical Activity Summary 06/2100Z to 07/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 365 km/s at 07/0044Z. Total IMF reached 7 nT at
06/2257Z. The maximum southward component of Bz reached -2 nT at
07/1631Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 356 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (08 Jun, 09 Jun, 10
Jun).
