At first I thought it was some kind of fireworks. It quickly changed from green to blue to reddish orange and after about 2 seconds went down behind the mountains. It was obvious at that point that it was not a firework although at first it did seem quite close. A few fragments seemed to break off from the main body of the fireball, but only the main Fireball remained intact as it descended.

Remarks
I was in the Antelope Valley of the Mojave desert in California I saw the fireball go more or less straight down. It passed out of view as it went down on the other side of the San Gabriel mountains either landing in the mountains, or landing in the Los Angeles Basin or landing in the ocean.
