Metal flying saucer flying at night flew towards my building, when it saw me come to the terrace again and hovered above my building

It was 11:50pm Saturday night. I had seen the UFO on Wednesday just after midnight. I wanted to see it again. When I went to my terrace , I recognized the white moonish bright circle flying in half circles in one spot below my apartment floor at the back of my building. I was standing on my terrace. It was a distance away in Stamford, but not as far away as it was on Wednesday. It much closer this time. Once I saw it from the terrace, It diagonally flew high toward my building and hovered high up above my building. I just watched it for a while , went back to my bedroom to charge my phone, and came back out to the terrace. it was still in the same spot. It flew hypersonically flew up down diagonal above my building, as I took some photos.
the flat part of the saucer on top and the dome part of the saucer on the bottom. It also flew sideways. I did not feel anxious this time, while I watched it.
