3 of us were walking on a path by tershishner creek west of nordegg after dark, we all saw a light brighter than any star/planet/satellite moving very fast go out of view behind the trees. i saw another light that looked exactly the same 30 minutes later flash on briefly without a trajectory or moving very slow and turn off again. an hour later we saw it moving again and this time went from a lateral movement, then changed 90 degrees to moving down and the brightness varied as we kept an eye on it for a short time.
