I live beside one of the biggest shopping centres in the city and I've got no
obstructions from due N to nearly due NW for lower elevation passes. At much
higher angles, I can follow it from nearly directly overhead to SSW.
In the past, I could tell when AO-51 was within view because the background
noise would drop significantly. Since I'm operating a portable station, I use
that to track it. Lately, it hasn't been as easy.

I've noticed that it's been rather quiet during later morning passes (say,
after 1500 UTC).

BTW, were you at the flea market at the Yellowhead Inn this past Saturday?
I've been to each one since I got my callsign 5 years ago and I'm sure that
this one had the most people. I was looking for a manual HF + 6 m tuner but
couldn't fine one, but there were lots of other items that I bought that I
could use.
It was a good opportunity to meet hams in person that I'd spoken to by radio,
including some from local nets. It was certainly a good way to spend two hours.
