IA. Analysis of Solar Active Regions and Activity from 15/2100Z to
16/2100Z: 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 (17 Feb, 18 Feb, 19 Feb).
IIA. Geophysical Activity Summary 15/2100Z to 16/2100Z: The geomagnetic
