Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 339 Issued at 2200Z on 05 Dec 2017
IA. Analysis of Solar Active Regions and Activity from 04/2100Z to
05/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 0 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be very low
on days one, two, and three (06 Dec, 07 Dec, 08 Dec).
IIA. Geophysical Activity Summary 04/2100Z to 05/2100Z: The geomagnetic
field has been at unsettled to minor storm levels for the past 24 hours.
Solar wind speed reached a peak of 611 km/s at 05/2100Z. Total IMF
reached 13 nT at 04/2106Z. The maximum southward component of Bz reached
-10 nT at 05/0901Z. Electrons greater than 2 MeV at geosynchronous orbit
reached a peak level of 365 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to minor storm levels on day one (06 Dec), quiet to
active levels on day two (07 Dec) and quiet to unsettled levels on day
three (08 Dec).
