Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 256 Issued at 2200Z on 13 Sep 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 are currently 1 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be very low
with a slight chance for a C-class flare on days one, two, and three (14
Sep, 15 Sep, 16 Sep).
IIA. Geophysical Activity Summary 12/2100Z to 13/2100Z: The geomagnetic
field has been at quiet to minor storm levels for the past 24 hours.
Solar wind speed reached a peak of 656 km/s at 12/2116Z. Total IMF
reached 16 nT at 12/2129Z. The maximum southward component of Bz reached
-12 nT at 12/2257Z. Protons greater than 10 MeV at geosynchronous orbit
reached a peak level of 138 pfu at 12/2100Z. Electrons greater than 2
MeV at geosynchronous orbit reached a peak level of 2410 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at unsettled to minor storm levels on days one and two (14 Sep, 15
Sep) and unsettled to active levels on day three (16 Sep). Protons are
expected to cross threshold on day one (14 Sep), are expected to cross
threshold on day two (15 Sep) and are likely to cross threshold on day
three (16 Sep).
