I saw something that looks identical to this light back in 1994 in Los Angeles while stuck in a traffic nightmare around dusk. I watched it stay in one spot for about 20 minutes, then it shot across the sky, hovered another 5 or so minutes then shot straight up. I thought it was a helicopter until it shot across the sky. I can't say it was aliens or anything, but I have no idea WHAT it was. I remember looking around to see if anyone else was watching it and a few seemed to be pointing. Weird indeed.
