While scanning the sky for strange clouds i noticed a white object approaching from the east. when it got close enough it looked similar to a craft i had seen enter a cloud but not come out of it in march 2017. i watched it until it was out of my sight. i saw another white object approaching from the same direction. i waited to observe it. ditto. no visible wings, no contrail, black band around the center. i watched it until it left my sight then saw a third object approaching from the same direction . it was a repeat of the first two. after the third object was out of sight i waited for a couple of minutes before getting in my car to continue shopping.
