1999-12-03 - Santa Clarita, CA - Circle

Streak across the sky moving from SE to NW, color was teal/silver irredescence. Holding out hand, size was thumb nail, above cirrus clouds did not dissapate but disappeared immediately.

I was traveling northbound on I 5 and in a late afternoon sky I saw a circle or disk shaped object that was a greenish silver and was irredescence in color. The streak lasted some 1/2 second and by holding out hand it was about the size of my thumb nail. I noticed it was above the thin layer of cirrus clouds. It was too big to be a shooting star. The sky was still blue and the sun was still in the sky. I was amazed by how bright the object was inthe daytime sky. It was moving faster than anythng I had seen before including shooting stars. The object came from behind me out of the southeast and traveled toward the northeast. Without dissapating, the object just disapeared. No jerking movment or obvious change of direction was observed. I couldn't tell if it had a tail of if I was observing the visual stretch of the object due to the speed. I don't think this was space junk because of the size of the solid part of the object.
