SDF Number 340 Issued at 2200Z on 06 Dec 2019
IA. Analysis of Solar Active Regions and Activity from 05/2100Z to
06/2100Z: 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 (07 Dec, 08 Dec, 09 Dec).
IIA. Geophysical Activity Summary 05/2100Z to 06/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 537 km/s at 06/1945Z. Total IMF reached 6 nT at
06/1211Z. The maximum southward component of Bz reached -5 nT at
06/1159Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 134 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on day one (07 Dec) and quiet to unsettled levels
on days two and three (08 Dec, 09 Dec).
