Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 15 Issued at 2200Z on 15 Jan 2019

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 no 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 Jan, 17 Jan, 18 Jan).

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 432 km/s at 15/2018Z. Total IMF reached 9
nT at 15/1805Z. The maximum southward component of Bz reached -5 nT at
15/1904Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 214 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (16 Jan) and quiet levels
on days two and three (17 Jan, 18 Jan).
