Bill,

I have on several occasions, while I am listening to my own signals (in CW) on the SAT's AO-07, FO-29 and VO-52, when they are LOS to the North of the US and have copied the signals down to -6 degrees on nights that there have Aurora alerts posted from several reflectors that I subscribe to. Most of the time my Northern LOS for these birds is 1 to 2 degrees when there are no alerts. Certainly no expert on this phenomenon, but I believe that the signals are enhanced beyond the normal range during the enhancement conditions.

...

I was giving a presentation at our club meeting called Working DX on the Satellites and afterwards someone had a good question: is it at all possible that tropo, skip, or other form of enhanced propagation can enable a contact via a satellite below the horizon?

It has never happened to me. Has it ever happened?
