Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 362 Issued at 2200Z on 28 Dec 2017
IA. Analysis of Solar Active Regions and Activity from 27/2100Z to
28/2100Z: 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 (29 Dec, 30 Dec, 31 Dec).
IIA. Geophysical Activity Summary 27/2100Z to 28/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 452 km/s at 28/0112Z. Total IMF reached 8 nT at
27/2112Z. The maximum southward component of Bz reached -5 nT at
27/2214Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 1545 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one and two (29 Dec, 30 Dec) and quiet to
active levels on day three (31 Dec).
