SDF Number 129 Issued at 2200Z on 08 May 2020
IA. Analysis of Solar Active Regions and Activity from 07/2100Z to
08/2100Z: 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 (09 May, 10 May, 11 May).
IIA. Geophysical Activity Summary 07/2100Z to 08/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 367 km/s at 08/0916Z. Total IMF reached 5 nT at
