As reported by the Cambridge Chronicle newspaper, Brad Kelly, a Somerville photographer, captured a photo of this meteor in sky over Harvard Square Saturday night.  Kelly shared a photo of the original photo — taken with a Nikon D300 — with Wicked Local Cambridge. For photo geeks, Kelly said, it was an 8-second exposure at aperture f8 on a tripod with a 20mm prime lens. (Copyright 2011 Cambridge Chronicle. Some rights reserved.)
