What caused the green horse image in MSNBC's Egypt coverage

Hmm, yes, I think you’re right. Each “horsefly” has a light source on the opposite side (opposite the center of the field).

Plus, the green color is an additional indication that it’s a reflection off of a coated surface, which is what a lens flare is.

I blame J.J. Abrams.

If you were to take the fire, remove the bright glare, and flip it around 180° around the centre of frame, it would match up with the so-called horse.
