Sitting on deck facing west saw white oval/round light moving slow with a halo around it.

As I was looking up I saw this white oval/round light moving slow with a halo around it. NO SOUND, but it was high. I saw it in a break in the high clouds. I watched to see it come out from the cloud it flew in or above. By the speed it was going it should’ve appeared in less than 10 seconds. It didn’t come back and I watched that spot for maybe 30 seconds. When I didn’t see it I got up and walked out so I could see more of the sky. There was high clouds as I said, but There was plenty of open space in the sky to see it. There was nothing to be seen. I watch the sky for maybe 8 or 10 minutes.
