Bright white orb that was silent moved north, then south then from west to east then back west.

Using Night vision Binoculars,I was looking for ufos.I observed an object up in the night sky at around 10 or 11 o'clock pm moving from South to North slowly. It looked like a star,it was small.when I flashed my light up in its direction, it stopped moving. If I hadn't been watching it, I would think it’s a star. I flashed the light again and it began moving back South, then turned and went from West to East or my left to my right and started moving in front of me and it went from a small start to a large orb bright white light, seemed brighter that the Sun, like it shimmered.Its at this point I picked up the infrared night vision binoculars again which I had put down to look with my naked eyes, and that's where I started to video. Its shaky because I didn't have time to get a tripod and my adrenaline was pumping. It moved across my vision up in the sky. I watched it move silently, it wasn't space junk or a plane, helicopter, drone, it moved intelligently and was completely silent. I flashed it again with my light and as seen, it got small again and moved back out into space.later it came back and moved right to left up on the sky and was hard to see unless you had the Infrared binocs on. I have been doing this for 3 years and have seen many objects moving up in the sky,but this one was different. It changed direction a few times, went from dim to super bright then dim again, and it was silent, like it was watching or observing me because I had flashed a laser up in their direction. Never at it of course.
