While every amateur text I've come across states that the D and E layers
disappear at night, they, in fact, do not. They rise to higher altitudes
and
remain ionized through background cosmic radiation.
----------------------------------------------------------------------
So I believe, and the elevated E layer during the night could also be
responsible for some of the single hop transcontinental openings on 6m -
unfortunately IMHO also called Auroral Es openings since they can occur
occasionally when the Aurora is 'quiet'. I have noticed similar openings on
40m at this QTH.
