Unexplained flying object that was observed by two witnesses and then vanished.

We are in a very low populated area with no outside lights or noises. The surrounding area is mostly pine trees. We were outside at about 5:50am on October 3, 2023, drinking coffee and looking at the stars like we do most mornings. Normally we will see stars and satellites. In this area it is rare to see aircraft at night. On this calm clear morning, we observed three large white lights close together in a triangle shape that appeared to be all part of the same craft. These lights appeared to be low in the sky and close to us. The lights moved from the East to the West at a slow and steady pace with no noise or disruption. There were no colored (red and green) lights like an aircraft. There was no noise like an aircraft. It was very low, seemed very close to us and made no sounds or wind movement at all. It was observed in the clear sky with no cloud cover, No wind, no noise, no other lights, and no obstructions from trees. Then it vanished. It didn't change direction or shoot into the sky. It just vanished/went dark as we were watching it and talking about it.
