The ever-awesome Bill Westphal contributes the following:
... Altadena WeatherCam caught an interesting image early this afternoon. Brought to my attention by WeatherCam viewer Carol Momsen of Altadena who wrote "What is that in the sky?" I went back through the archives this evening and found this image taken at 13:06 hrs. I don't think it looks like a plane. And it doesn't really look like a bird either.

(We've blown up the picture of the object and inset it in the picture. Swamp gas? Experimental aircraft? Close encounter?)
(First celebrity picture ... first UFO. We're taking the rest of the week off ...)
