Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 225 Issued at 2200Z on 13 Aug 2017
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 is currently 1 numbered sunspot region on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be very low
on days one, two, and three (14 Aug, 15 Aug, 16 Aug).
IIA. Geophysical Activity Summary 12/2100Z to 13/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 771 km/s at 12/2146Z. Total IMF reached 6
nT at 12/2357Z. The maximum southward component of Bz reached -4 nT at
13/0537Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 978 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and three (14 Aug, 16
Aug) and quiet levels on day two (15 Aug).
