SDF Number 334 Issued at 2200Z on 30 Nov 2019
IA. Analysis of Solar Active Regions and Activity from 29/2100Z to
30/2100Z: 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 (01 Dec, 02 Dec, 03 Dec).
IIA. Geophysical Activity Summary 29/2100Z to 30/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 416 km/s at 30/1200Z. Total IMF reached 7
nT at 30/0922Z. The maximum southward component of Bz reached -5 nT at
29/2123Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 504 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one and two (01 Dec, 02 Dec) and quiet to
unsettled levels on day three (03 Dec).
