Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 350 Issued at 2200Z on 16 Dec 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 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 (17 Dec, 18 Dec, 19 Dec).
IIA. Geophysical Activity Summary 15/2100Z to 16/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 381 km/s at 15/2200Z. Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 192 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (17 Dec) and unsettled to
minor storm levels on days two and three (18 Dec, 19 Dec).
