Location: Fremont,  ca. 

I saw these back in September.  I talked about this with the people you will hear in the videos.   By the time I turned on my camera,  they were over it.   

This drifting light caught my eye.   I watched it for a while and it kept changing shapes,  like a star twinkling.  I have another video and a still, as well.   Happy to share those if you're interested. 
None of this is enhanced or altered in any way.
Anyone have any ideas about what this could be?
