Suprise opening to South America on 28 MHz - Tues 10th Mar 2020

On Tuesday the 10th of March 2020, I had the radio listening on the FT8 frequency on 28 MHz from noon on.

I heard very little except for late in the evening when a signal from Chile was heard at 17:50 UTC and several signals from PY2XS in Brazil at 20:30 UTC.

This was about two hours after local sunset and was at a time when you'd expect to hear nothing on the band.
