My question is if there have ever been unusual propagation effects been observed, during very strong geomagnectic activity. Things like Aurora on VHF or a duct for LF? The pole and what happens there in the auroral oval is an interesting imagination. I think (not being a propagation expert) it is always worth watching and transmitting. 73, Stefan/DK7FC
