Hello All,

Is there anybody who can tell me what is the real connection between 
the Moon and the TP propagation. I don't get the fact with 27-29days.
Normally the moon have a role to play on our (Earth) magnetosphere 
but I don't know if there si a cycle of 1 lunar month connecting with 
"good propagation".

I'm a beginner on TP and I'm interested to understand the propagation 
facts on MW, especially about 0.7-2MHz.
Maybe some readings? Especially scientific one if there are some.

Many thanks.
