SDF Number 130 Issued at 2200Z on 09 May 2020
IA. Analysis of Solar Active Regions and Activity from 08/2100Z to
09/2100Z: 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 (10 May, 11 May, 12 May).
