These are flashes from a 3"x5" glass signal mirror, 44 miles away. This was a particularly clear day in Los Angeles - normally the air would not be clear enough for this. The mirror is a military issue MIL-M-18371E with retroreflective mesh aimer, as described at http://www.equipped.com/phony_signal_... . Sea Kayaker magazine had a nice 5 page review of signal mirrors, here: http://www.seakayakermag.com/2001/01O... .
