All my observation ''windows'' are miserable < mag 9.0! c) Any dark-sky challenged folks or city dweller seen this?? Binos? >>>I will answer them in reverse order: c) Flashes have been observed from the city at +0 magnitude brightest. The flashes are instantaneous and you have to be looking right at them to see them. b) It is made more difficult by the fact that the flashes are unpredictable at this time.The background brightness without flashes is +7 under good phase conditions to below +9 at worse phases. a) to get a feel for what to expect, you should consider looking at the entire arc of a STARSHINE pass, possibly using Chris Peat's marvelous online chart capability from GSOC. The flashes may appear (or not appear) at any point in the arc. There is no apparent flash period at this time since they are reported to occur at random times. The number of flashes reported to this point range from 0 (on a direct overhead pass) to 7 on a 50 degree elevation pass. Intervals between flashes are highly variable ranging from about 5 seconds at the shortest interval to over a minute for the longest interval. Paul Paul D.
