Strange octagonal shaped anomaly stands still mid air over San Martin, CA

A strange black octagonal shaped object with a hole in the middle has been observed in the sky over San Martin, California on November 1, 2020. 


According to the photographer; if it was a balloon it will be moving but this object stands still mid air, it does not move at all. Later on in the footage the photographer suggests that it is a tire, but he is not sure. 

Since the shape of the object is octagonal, it is very questionable whether it is a tire, moreover, like a balloon, a tire will be moving too but that does not happen. Mufon report here.
