Fine Structure

A friend posted this image on twitter during the early part of the Venus transit today. Note the white dot in the lens flare on the bottom right.

I think it's pretty awesome that the transit can make it into a somewhat normal picture during the day, however I'm not completely convinced that this was actually Venus. On one hand, that was pretty close to the position of Venus when he posted the picture but if the red half-circle is supposed to be a reflected image of the Sun then the scale seems to be a bit off. Venus seems very large in comparison to the approximate size of the Sun given the part of the circle that we can see.

I'll put it out there for anyone who has more detailed knowledge of camera optics. What do you think? Did Venus make it into this shot?

Update: Phil Plait thinks it's just some conveniently placed lens flare.
