While doing a CE-5 in Sunset, Tx we spotted this red pulsating object flying towards the south. It does not make any noise nor does it have the red and green navigation lights that would make me say it is not an airplane. It could be a satellite but I don’t think so since it seemed pretty low and moving fairly slow for a satellite. It is filmed using Yukon Ranger digital night vision monocular so it will not display colors, just grayscale.
