Thanks for sharing this. I have never before seen the phenomena. Not
only is it interesting for students (and retired physics teachers) to
compute the angular rates and moon rise time involved; it's just simply
beautiful!

Subject: [Phys-L] Trick photography?
If you've never seen a tele-video of a distant terrestrial scene
silhouetted by a rising moon, look at==> http://vimeo.com/58385453.
The casual observer often complains that this must be a manipulated
photoshop type trick.
It is an interesting exercise for students to investigate this by
calculating, and comparing, the speeds of the terrestrial and lunar images
across the camera film/digital sensor.
More than sufficient data is available from the video clip, its
commentary, and known lunar data.
