We witnessed a low flying object approaching slowly from the west going eastward, while I was driving home on 9/15/‘23 around 3:30 P.M.

While driving up a hill and approaching our driveway, I noticed an object flying low over the neighborhood houses. As it came closer, I noticed that it was not a plane nor a helicopter and it was not flying south towards the Tucson airport - which is the usual flight route for planes. Instead it was flying over the back of our house and going east towards Mount Lemmon. Immediately, I knew that it was unusual and I asked my husband to look at it and tell me what it was. He told me that it was a UFO. When I parked the car in the garage - the silvery looking disc/object disappeared from view. We were both in shock. This happened on Friday afternoon at about 3:30 P.M.
