Looking up in the night sky at the stars to the east. many of the stars appearing same in size and brightness. i noticed one of these star like objects move steadily to the northwest. i could see it move for about 10 seconds then called my wife and daughter to look and they saw for about 20 seconds until it went out of sight. my son came out after and i explained what had transpired. so we kept looking up at the same altitude about 60 degrees in the sky. five minutes or so later we see the same object moving across the sky from north to south for about 40 seconds. i tried to video, but too far away for my phone camera. as i used the camera my son watched the object and he said it just disappeared into the night sky?
