However, it is also visible in the "raw" video (example)...: http://venustransit.gsfc.nasa.gov/data/kio...n/phase/ingress

My guess is it's a diffraction effect in the optics. That video you posted also shows what appear to be diffraction fringes on Venus' dark disc, noticeable before ingress. Depending on how the optics and supports inside the telescope are oriented, you might get a diffraction "plane" that by chance matches with the Sun's limb slope at that point.

Here is a cross view stereo pair of the Venus transit with some air traffic.


What a catch, wauw!

Sun photographer extraordinaire Thierry Legault also caught some traffic in his Venus transit shot: The Hubble!

(All his sun pics are amazing, btw...)
