Daytime disc shaped UFO over Griffith Observatory, CA

This daytime picture of a disc-shaped object was taken on 25th November 2009 at Griffith Observatory, California.

“I was taking pictures of the Hollywood sign and the Griffith Observatory. I had just parked my vehicle and was walking towards the Observatory and decided to snap a few shots of the building.
I didn’t notice the object until I uploaded the pictures on my computer. That’s when I noticed this odd shape in the sky in one of my pictures. I’ve posted two pictures.
The first one is where the object is to the right of the screen. The second was taken about a minute afterwards from a different angle.”
