Circle over Bozeman, MT

The report, as filed

I sent report to your email. I hope that works, my tablet won't copy/paste. ((name deleted, Bozeman, MT. We spoke this evening. ((ADDENDUM FROM WITNESS; ORIGINAL E-MAILED REPORT I walked out onto our patio with my daughter and immediately noted how bright Venus was that morning. I showed my grand daughter how, just before sunrise, she could use her hand to measure from the sun to a point in the sky and at noon that day find and see Venus at mid day. A few minutes later I was looking directly overhead to see the big dipper when I noticed a very bright object to the north. I thought at first it might be the ISS, but it was travelling almost directly north to south. After maybe a minute it suddenly became very dim, but I could still see it clearly. About this time my daughter lost interest. Just a few seconds after the object became dim it began to accelerate faster than any satellite I have watched. When the object was directly over head still travelling very fast it performed a perfect 450 degree turn and sped away to the east and vanished. When the object performed the perfect counter clockwise circle plus 90 degrees it either left a vapor trail or it was so fast that my eyes were seeing what you see when a child twirls a sparkler. This event happened about one hour before sunrise. I would speculate that the object was reflecting sunlight and became dim as it reduced altitude. When helicopters patrol transmission lines and reach a point where the line makes a 90 degree turn the pilot will do a circular 450 degree pattern returning to the end point and continue down the line. This object performed the exact maneuver at an incredible speed. I would also note that the circular turn made by this object was absolutely symmetrical. I have been a true UFO sceptic all my life and have never had the remotest inclination to believe in them until this event on Tuesday.
