I was sitting in a chair opposite my mother and saw a glowing object while glancing through her patio window doors to cloud level. At first i thought it was a reflection from lighting inside her condominium, but realized this was not the case and that it had a density and inner glow.It looked like a piece of thick thread that had been squeezed together and remained in that form, or a bit like intestine. It hung in the sky for almost two minutes before moving backwards very fast. Becoming smaller quickly until it reached pinpoint size in the blue sky and then was gone. It was exciting to see, and to see it leave. Not something everyone has a chance to witness.
