star-like object in slow circular path suddenly speeds across sky in bright white cigar shape then disappears in cloud bankDriving home tonight near shoreline of lake Ontario, about 5 houses from my home, I observed a star-like light way above my house, moving in a tight slow circular path. Other than motion, it looked like a star. Then it sped off in a curved path much like a nike swoosh logo across the sky southward toward the city and disappeared in a cloud bank. When it flew across it looked like a bright white cigar shaped light. Not sure if shape truly changed or the extremely fast motion made it appear that way. I could see the clouds light up as it moved through them then it was gone. I have worked night shift for 22 years and having the opportunity always look up in the sky for the chance to see something extraordinary, and tonight it happened.
