Hi I just saw the same thing you described. I also live in Anaheim. I took a video of it on my cellphone, but it looks grainy. I have also never seen anything like it.
Here is a link to the video of that thing I saw in the sky. I uploaded the video to YouTube.
Note: The witness reported this sighting to another Blog (the Vike Factor). The case was forwarded to me for posting. I don’t know what case that the witness is referring to.
