Two lights one behind the other approximately 500 feet apart appeared at 45 degrees from the from the southwest. They were weak at 1st and increased in intensity until it was directly overhead. It Departed the same way it arrived. It disappeared at about 45 degrees from vertical towards the Northeast. There was no sound whatsoever. It didn't look that high in altitude. To guess I would say around 1,000 feet. I watch the sky at night all the time and this is the first time I've seen something like this. I see satellites all the time and iridium flashes. I see meteors and I see the space station. Nothing of this Nature has ever appeared before period
