We observe the cylinder from the front of my house and it appeared to be quarter-mile away over a canyon. it spun vertically and horizontally but didn’t move from the position overhead for five minutes. it was a gray reflective surface or a black surface depending on how the sun hit it. estimated at 30 feet long and 10 feet wide similar to a cigar tube. it started to rise almost straight up while continuing to turn. add about 1000 feet altitude it change directions and started moving south west. after five minutes it passed over our heads at about 1500 feet and disappeared over our house. my brother and my friend observe the object or 15 or 20 minutes with me and no one has any idea what it really is.
