Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 347 Issued at 2200Z on 13 Dec 2018
IA. Analysis of Solar Active Regions and Activity from 12/2100Z to
13/2100Z: 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 (14 Dec, 15 Dec, 16 Dec).
IIA. Geophysical Activity Summary 12/2100Z to 13/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 452 km/s at 13/0216Z. Total IMF reached 5 nT at
13/1625Z. The maximum southward component of Bz reached -3 nT at
13/1620Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 2256 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one and two (14 Dec, 15 Dec) and quiet to
unsettled levels on day three (16 Dec).
