SDF Number 274 Issued at 2200Z on 30 Sep 2020
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 Oct, 02 Oct, 03 Oct).
IIA. Geophysical Activity Summary 29/2100Z to 30/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 642 km/s at 30/1435Z. Total IMF reached 5
nT at 30/0242Z. The maximum southward component of Bz reached -4 nT at
29/2346Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 29293 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (01 Oct), quiet to unsettled
levels on day two (02 Oct) and quiet levels on day three (03 Oct).
