    Sun was at -11.4 degrees, which is dark enough.
    
    Two observations are usually much more conclusive than magnitude:
    1. Direction ('going left' = 270 degrees = 9 o'clock).
    2. Speed, e.g. the time to pass the distance between the tips of your spread
    thumb and index fingers (at straight arm distance) or the same distance as
    between two known stars, or the field-of-view of your binoculars (specify!).
    
    With satbase.tle, I find just one 'going left' Dir=280 degrees within
    predicted mag.limit +16 and +- 3 minutes : #16592 NOSS 7 r, but it is
    predicted at +6 mag and going between Jupiter and delta Geminorum 11:03:50
    (16 seconds for the distance alpha-beta)
