White Streak (FRAME 3)

  • PeriousXandonius by PeriousXandonius

    Hey guys, I'm new to Asteroid tracking and examining images in general. SO i was wondering what the heck could the white streak in frame 3 be? fast moving body? light distortion?

    Its a Fast Moving Object, or FMO for short.
    The exposure time for these images is around 30 seconds. A lot can fly by in that time.
    Ref: Exposure time and frame width

    Possible sources I'm aware of:

    • Satellites: Relative high probability. Its kinda crowded out there if you ask me.
    • Meteors: Variable probability based on there size. (smaller == higher, although if there to small they don't light up.)
    • Airplanes: Low chance, and general with low visibility. Although there navigation light blips should stand out.
      (Just in case. FMO's only show in one frame ... or else its something else.)

    Oh alright thanks MvGulik!
