optical flash signaling?

Filed under: Letters from Ionia — Tags: — zankaon @ 5:19 am

How far away can the oxygen signature in our atmosphere be detected? Indicative of photosynthesis. How far away can optical flashes from orbiters/satellites in Moon orbit be detected? A sign of technological civilization from afar? Is this much more effective than radio wave detection?  TMM

Perhaps enhanced detection of non-repeating signals embedded in noise, might be useful.
