Huge Green Bar

  • vigilantice by vigilantice

    This image came up while classifying galaxies. I assume the huge green bar is the thing I'm supposed to be looking at. I'm just not entirely certain what it is or if its a regular occurrence.

    This is a satellite trail.

    The satellite reflects the sunlight and because it moves so fast it only gets picked up in one filter. Usually green, but blue and red streaks are possible too !
