Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 194 Issued at 2200Z on 13 Jul 2017

IA.  Analysis of Solar Active Regions and Activity from 12/2100Z to
13/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C8 event observed at
13/2005Z. There are currently 2 numbered sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is expected to be very low
with a chance for a C-class flares and a slight chance for an M-class
flare on days one, two, and three (14 Jul, 15 Jul, 16 Jul).

IIA.  Geophysical Activity Summary 12/2100Z to 13/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 463 km/s at 12/2138Z. Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 666 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and three (14 Jul, 16
Jul) and unsettled to active levels on day two (15 Jul).
