Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 264 Issued at 2200Z on 21 Sep 2019
IA. Analysis of Solar Active Regions and Activity from 20/2100Z to
21/2100Z: 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 (22 Sep, 23 Sep, 24 Sep).
IIA. Geophysical Activity Summary 20/2100Z to 21/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 373 km/s at 21/0645Z. Total IMF reached 7
nT at 21/0604Z. The maximum southward component of Bz reached -6 nT at
21/0717Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 954 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on day one (22 Sep), quiet to active levels on day
two (23 Sep) and quiet to unsettled levels on day three (24 Sep).
