Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 267 Issued at 2200Z on 24 Sep 2017
IA. Analysis of Solar Active Regions and Activity from 23/2100Z to
24/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 2 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 (25 Sep,
26 Sep, 27 Sep).
IIA. Geophysical Activity Summary 23/2100Z to 24/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 367 km/s at 23/2120Z. Total IMF reached 7 nT at
24/1722Z. The maximum southward component of Bz reached -6 nT at
24/1836Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 12883 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (25 Sep), quiet to unsettled
levels on day two (26 Sep) and quiet to minor storm levels on day three
(27 Sep).
