[UK-CONTEST] Night Time Es

[Richard Newstead]

Night time Es are quite a common occurrence throughout the year. Such  
events are often missed. You can see one here:

The blob at about 0300 is Es. This was an observation in September.

I guess that such events may be the result of Es at the magnetic conjugate  
in the Southern hemisphere?

The E layer is much more active and important at HF than is suggested by  
many amateur radio articles on propagation. For the interested, I can  
recommend "Ionospheric Radio" by Davies ISBN 0 86341 186 X.
