    It is possible that western US can see the flashes Rainer has seen -
    Europe may be losing it's chances from today on. Low in NNW around
    midnight. Or, more accurately and general, around RA 16:30 Dec.+50.
    (Apologies, Rob, your graph was made for 7:30 local time instead of UT,
    but the RA/Dec is OK)
    
    There don't seem to be any flash events for Australia, and for South
    Africa it rises some 10 degrees from the flash track, and just gets
    further away.
