Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 259 Issued at 2200Z on 16 Sep 2017
IA. Analysis of Solar Active Regions and Activity from 15/2100Z to
16/2100Z: 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
on days one, two, and three (17 Sep, 18 Sep, 19 Sep).
IIA. Geophysical Activity Summary 15/2100Z to 16/2100Z: The geomagnetic
field has been at unsettled to major storm levels for the past 24 hours.
Solar wind speed reached a peak of 821 km/s at 16/1435Z. Total IMF
reached 8 nT at 16/0356Z. The maximum southward component of Bz reached
-7 nT at 16/0345Z. Protons greater than 10 MeV at geosynchronous orbit
reached a peak level of 2 pfu at 16/0145Z. Electrons greater than 2 MeV
at geosynchronous orbit reached a peak level of 22886 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to minor storm levels on day one (17 Sep) and quiet to
active levels on days two and three (18 Sep, 19 Sep).
