Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 259 Issued at 2200Z on 16 Sep 2019

IA.  Analysis of Solar Active Regions and Activity from 15/2100Z to
16/2100Z: 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 (17 Sep, 18 Sep, 19 Sep).

IIA.  Geophysical Activity Summary 15/2100Z to 16/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 485 km/s at 16/0123Z. Total IMF reached 6
nT at 15/2108Z. The maximum southward component of Bz reached -4 nT at
16/0124Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 1745 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (17 Sep, 18 Sep)
and quiet levels on day three (19 Sep).
