I was sitting in the den. something got my attention and when i looked up into the dining room a bright round light entered from the kitchen. moving south about same speed as brisk walk it traveled in straight line about five feet above floor ang was about the dia of a basketball. i heard no sound. it passed thru window while i sat dumfounded. three hours later when i let my dog out to pee a larger light about twenty feet in dia to my east moved in a straight horizontal line to the north. it was about two hundred yards away and three hundred feet in altitude. i watched it go into warp speed in a nano second.
