Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 331 Issued at 2200Z on 27 Nov 2017
IA. Analysis of Solar Active Regions and Activity from 26/2100Z to
27/2100Z: 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 (28
Nov, 29 Nov, 30 Nov).
IIA. Geophysical Activity Summary 26/2100Z to 27/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 494 km/s at 27/1404Z. Total IMF reached 13 nT at
27/1354Z. The maximum southward component of Bz reached -5 nT at
27/0252Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 602 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (28 Nov), quiet to minor
storm levels on day two (29 Nov) and quiet to active levels on day three
(30 Nov).
