Did you know? Here’s a space weather and radio propagation educational tidbit – from http://SunSpotWatch.com – at 14:00 UTC on 2017-05-30:

The peak electron density of the ionosphere usually occurs in its ‘F region’. The ionosphere’s F-region is divided into two regions known as F1 and F2, though a third sub-region has been observed over the equator during certain conditions.

The F1 region is the lower of the 2 F-regions of the ionosphere and isn’t always present.

The F-regions of the ionosphere are ionized with extreme ultraviolet light (EUV).
