SDF Number 335 Issued at 2200Z on 01 Dec 2019
IA. Analysis of Solar Active Regions and Activity from 30/2100Z to
01/2100Z: 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 (02 Dec, 03 Dec, 04 Dec).
IIA. Geophysical Activity Summary 30/2100Z to 01/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 407 km/s at 30/2151Z. Total IMF reached 5 nT at
01/0548Z. The maximum southward component of Bz reached -3 nT at

peak level of 214 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on day one (02 Dec) and quiet to unsettled levels
on days two and three (03 Dec, 04 Dec).
