My son and a few of his friends were outside when they seen it appear, they yelled for my husband and I to look. we all seen it move up and then a little to the right. It hovered there for quite awhile this time(we've seen it before) One of the kids was able to get a decent photo of it this time. It remained there for about 10 minutes and then suddenly disappeared like lights out. About 10 minutes later it reappeared only lower in the sky and then went straight up and hovered then disappeared again. No aircraft was in the sky at that time and the sky was clear.
