Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 14 Issued at 2200Z on 14 Jan 2021

IA.  Analysis of Solar Active Regions and Activity from 13/2100Z to
14/2100Z: 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 (15 Jan, 16 Jan, 17 Jan).

IIA.  Geophysical Activity Summary 13/2100Z to 14/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 409 km/s at 13/2112Z. Total IMF reached 5 nT at
14/1216Z. The maximum southward component of Bz reached -2 nT at
14/1814Z.  Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 261 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one and two (15 Jan, 16 Jan) and quiet to
unsettled levels on day three (17 Jan).
