I was watching T.V. with my dad and all of a sudden the T.V. turned off. It does this time to time so I didn't think much of it at first, but then I looked up through the large sky light and saw what appeared to be, at first glance, a red star. All of a sudden I saw this glowing red object move really quick in one direction and then back the other. It would slow down and stop sometimes, sometimes it would move slow like a satellite, but then it would move fast again in one direction and then the other. This seemed to be at least 20,000 feet high, the bright red light illuminated around the object in the sky and did not flash. There was no sound, but the way in which it moved was unlike any aircraft I've seen or imagined of ever seeing. I have an astronomy laser and know what lights look like in the sky, and this was not anything like that. I watched it fly for over an hour. I saw it around 10pm or so to 11 or so and then went back outside in my backyard at 1am before going to bed and saw that it was still outside. The sky was filled with stars, and this one glowing red ufo was there moving around in all sorts of amazing ways, one that I will never forget is how it once shot up so fast that the light was getting dimmer and dimmer until it was gone, but then it came back within a minute. As if it elevated very far up and dropped back down. I am a videographer, and tried to film it but I couldn't see stars or the object on my camera. My cameras weren't made for astrophotography, and the object was like I said probably over 20,000 feet so it wasn't something that would be easy to film. Overall I know it wasn't a plane or helicopter, I am sure it wasn't a light or toy, and I don't know why there would be some drone that could move like that or that would be illuminating a red light. Either way this UFO was up above my house and Guerneville for at least 3 hours and I wouldn't doubt if it was there much longer. What exactly it was doing I don't know but it gave me the creeps. Amazing, scary, but an exciting experience and I really believe that what I saw was not of this world. I hope to see it again, thought about what if I flashed my astronomy laser up, if it would come closer… Maybe I will try that if I see it again. I am from LA and it makes so much more sense I would see this where I am living now, in the middle of nowhere, Guerneville CA. Whoever would see it or however many people would see it, it would not be as big of a deal as if it was in a big city like LA or NY.
