Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 48 Issued at 2200Z on 17 Feb 2020

IA.  Analysis of Solar Active Regions and Activity from 16/2100Z to
17/2100Z: 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 (18 Feb, 19 Feb, 20 Feb).

IIA.  Geophysical Activity Summary 16/2100Z to 17/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 360 km/s at 17/2004Z. Total IMF reached 6 nT at
17/1901Z. The maximum southward component of Bz reached -6 nT at
17/1901Z.  Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 383 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one, two, and three (18 Feb,
19 Feb, 20 Feb).
