SDF Number 182 Issued at 2200Z on 30 Jun 2020IA. 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 Jul, 02 Jul, 03 Jul).
IIA. Geophysical Activity Summary 29-2100Z to 30-2100Z

a peak level of 163 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to unsettled levels on day one (01 Jul) and quiet levels
on days two and three (02 Jul, 03 Jul).
