Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 46 Issued at 2200Z on 15 Feb 2020

IA.  Analysis of Solar Active Regions and Activity from 14/2100Z to
15/2100Z: 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 (16 Feb, 17 Feb, 18 Feb).

IIA.  Geophysical Activity Summary 14/2100Z to 15/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 366 km/s at 15/0942Z. Total IMF reached 6
nT at 15/1706Z. The maximum southward component of Bz reached -4 nT at
15/0952Z.  Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 799 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on day one (16 Feb) and quiet to unsettled levels
on days two and three (17 Feb, 18 Feb).
