Report of Solar Geophysical Activity

Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 186 Issued at 2200Z on 04 Jul 2016

IA.  Analysis of Solar Active Regions and Activity from 03/2100Z to
04/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 0 numbered sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is expected to be very low
on days one, two, and three (05 Jul, 06 Jul, 07 Jul).

IIA.  Geophysical Activity Summary 03/2100Z to 04/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 513 km/s at 04/0342Z. Total IMF reached 7
nT at 03/2115Z. The maximum southward component of Bz reached -4 nT at
03/2124Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 144 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (05 Jul, 06 Jul, 07
Jul).
