Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 364 Issued at 2200Z on 30 Dec 2017
IA. Analysis of Solar Active Regions and Activity from 29/2100Z to
30/2100Z: 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 (31 Dec, 01 Jan, 02 Jan).
IIA. Geophysical Activity Summary 29/2100Z to 30/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 418 km/s at 30/1755Z. Total IMF reached 6 nT at
30/0632Z. The maximum southward component of Bz reached -4 nT at
30/1327Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 965 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on days one and three (31 Dec, 02 Jan)
and unsettled to minor storm levels on day two (01 Jan).
