A Quincy reader who does not want to be identified took this photo of a blue light in the sky over the marshes along Post Island Road. Did you see it? Any idea what it was? A friend suggested it was a smurf entering heaven. Facebook readers lean toward E.T. and Twilight Zone theories.

Another reader, Tom Burris, saw the light at about 10 p.m. Friday over the Montclair neighborhood. Definitely trending.

"It was a constant blue light that was coming through the clouds," he said. "It did not move at all and was something I have never seen before." Meanwhile, over on Facebook.com/patriotledger, Patti Donahue has the most likely explanation with the photo of the Fore River Bridge she posted. Burris said he was looking south, in the direction of the bridge, when he took his photos.
