2003-06-08 - Oakley, CA - Light

2 lights merge, then disappear.

First off, I would like to say that I know how planes in the night sky look and behave since I live near local and intl. aiports. But on to what I saw. At around 10pm PST, I was driving due west through Knightsen to Oakley. I was on farming roads, so I had a pretty unobstructed view of what I saw. So, as I'm looking at the West horizon around Mt. Diablo, I see this fairly large orange light that was stationary off in the distance. I keep looking at it while i'm driving, and then a I see a smaller orange light off to the right of the first larger orange, and its making it way towards the bigger light. The smaller light continues to go toward the bigger light until they merge together. The bigger light completely envelops the small one. At this point i'm excited because i've never seen anything like this before. so I keep watching waiting for the smaller light to emerge signifying that it is just an airplane, but it doesnt. at that point trees cut off my vision of the event, and a few minutes later when i regain my viewpoint, the lights are gone. don't what it was. i'm just hoping that someone else might have saw something as well.
