Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 268 Issued at 2200Z on 25 Sep 2017
IA. Analysis of Solar Active Regions and Activity from 24/2100Z to
25/2100Z: 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 likely to be low with a
slight chance for an M-class flare on days one, two, and three (26 Sep,
27 Sep, 28 Sep).
IIA. Geophysical Activity Summary 24/2100Z to 25/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 455 km/s at 25/0758Z. Total IMF reached 10
nT at 24/2216Z. The maximum southward component of Bz reached -9 nT at
24/2230Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 1050 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on day one (26 Sep), quiet to minor storm levels
on day two (27 Sep) and active to major storm levels on day three (28
Sep).
