The following exert is an eye witness statement. Please read into it what you will. This has been reported to mufon who I am sure are investigating:
I was driving from foster city to sacramento. i look at the sky all the time and the object was very clear in front of me. i thought it might be a plane but i’m familiar with ufos and seem to notice them more than most people who mistake them for stars or planes. because it was just hovering there, it did not appear to be a plane. eventually it dimmed and appeared to take a “plane” form, with red and blue lights, however it quickly sped across the horizon within seconds, way too quickly for a plane, and found a new spot to hover in. i drove as far as i could see it and then it was out of my sight. it was not very exciting so it didn’t affect me, just interesting.
