Shadow of Skylab on the Earth

  1. Jan 4, 2013 #1
    Please ignore the UFO reference and watch for 5 seconds in the below link. One can see the shadow of Skylab on the Earth. Skylab is in a 235 mile orbit above the surface of the Earth. Clouds are about 5 miles above the surface of the Earth. So the camera capturing the images is at least 230 miles from the shadow. Why is the shadow so large?

    I don't see Skylab shadow, all I see are camera artifacts.

    Camera artifacts? Please explain how that relates to the "shadow" image on the left side of the video.

    OK, I see it now - some schmaltz on the camera lens. More light from bright clouds drowns it out. Less light from the dark blue oceans make it more visible.
