SDF Number 153 Issued at 2200Z on 02 Jun 2019

IA.  Analysis of Solar Active Regions and Activity from 01/2100Z to
02/2100Z: 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 (03 Jun, 04 Jun, 05 Jun).
