Thought it was a small white cloud in a blue sky. Comet shaped head, short con trail off each back edge, small appearing con trails between longer tails.I was leaving a building facing west. Saw a single white cloud appearing object in the sky to the east. I had to bend my head backward slightly to see it. I could tell it was moving to the east. No other aircraft were in the area. I would guess it was 10,000 to 15,000 feet high. The entire object was white. I called my daughter about 20:00. She ask me if I had seen the object in the sky. They observed it and said it took about 35 minutes for it to get closer to the ground and appeared to be white and bigger than a jet airplane. It decended straight down and disappeared in a southerly direction. 5 people witnessed it from their home. There was nothing on the radio or T.V. about it. They saw 2 amber flashes of light from the object.
