Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 176 Issued at 2200Z on 25 Jun 2017

IA.  Analysis of Solar Active Regions and Activity from 24/2100Z to
25/2100Z: Solar activity has been at very low levels for the past 24
hours. 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 (26
Jun, 27 Jun, 28 Jun).

IIA.  Geophysical Activity Summary 24/2100Z to 25/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 524 km/s at 25/1611Z. Total IMF reached 10
nT at 25/1202Z. The maximum southward component of Bz reached -8 nT at
25/1018Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 213 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and three (26 Jun, 28
Jun) and quiet levels on day two (27 Jun).
