Mothlike craft over angels camp CAIt looked like a glowing white ball with some kind of light radiating out from the sides, like moth wings... but I didn't observe movement in the "wings". It was hard to tell how large it was as it was hard to tell how close it was at first. I thought it might be some kind of satelite, but then I noticed it was close, very close. I couldn't have been larger 20 feet in diameter as it landed in the trees and became hidden as it landed.This was sighted during a big music festival. A woman called me over to witness it as she has sighted it just before I arrived. There was a very large bonfire going on one area of the fairgrounds and there was lots of music and activity. She viewed the object over the bonfire and was watching it move over the main stage area when I arrived. I watched with her as it moved over the fairgrounds. It headed out towards the hills and I assumed it would vanish over the hill, but it actually went into the hill, thats when I determined it had been traveling very close to the earth and was pretty small. It floated over the treetops on the hill for a moment then decended in to the wood. The glow of the craft remained, on the ground for a moment then went off. We stood watching for a minute or two to see if it would rise again but the wood remained dark.
