Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 194 Issued at 2200Z on 13 Jul 2015

IA.  Analysis of Solar Active Regions and Activity from 12/2100Z to
13/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 3 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 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 unsettled to minor storm levels for the past 24 hours.
Solar wind speed, as measured by the ACE spacecraft, reached a peak
speed of 700 km/s at 13/0104Z. Total IMF reached 10 nT at 13/0343Z. The
maximum southward component of Bz reached -9 nT at 13/0545Z. Electrons
greater than 2 MeV at geosynchronous orbit reached a peak level of 593
pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to minor storm levels on day one (14 Jul) and quiet
levels on days two and three (15 Jul, 16 Jul).
