Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 193 Issued at 2200Z on 12 Jul 2017

IA.  Analysis of Solar Active Regions and Activity from 11/2100Z to
12/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 2 numbered sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is likely to be low with a
slight chance for an M-class flare on days one, two, and three (13 Jul,
14 Jul, 15 Jul).

IIA.  Geophysical Activity Summary 11/2100Z to 12/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 540 km/s. Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 658 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on day one (13 Jul), unsettled to active levels on
day two (14 Jul) and quiet to active levels on day three (15 Jul).
