    I find it helps to go out one night and line up with a star. E.g. I know
    that the flare will be at az 258 el 72.
    
    So I run planetarium software, step it through different times, and note
    that a bright star will be at that position in the sky at 21:30 the
    previous night.
    
    I go out at night, note exactly where I stand & where the star is (just
    touching the top of a tree ...).
    
    Then I know where to look when I go out in daylgiht.
