SDF Number 255 Issued at 2200Z on 11 Sep 2020
IA. Analysis of Solar Active Regions and Activity from 10/2100Z to
11/2100Z: 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 (12 Sep, 13 Sep, 14 Sep).
IIA. Geophysical Activity Summary 10/2100Z to 11/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 321 km/s at 11/1823Z. Total IMF reached 5 nT at
10/2304Z. The maximum southward component of Bz reached -4 nT at
