While camping at Gooseberry campground we were looking for satellites using night vision glasses at approximately 11pm. We had seen a number of satellites that night and were surprised to see a bright flaring star-like object in the south vectoring towards us and away from the moon. We thought it was a plane initially but it was clearly in space, had no flashing lights or coloured lights. The 1st vehicle vectored from the moon position silently towards us from the south and brightened dramatically on approach. As it faded a few seconds later to our surprise a second vehicle appeared on the same trajectory which brightened, faded and fell in behind the 1st vehicle. Both vehicles proceeded nose to tail for 30 seconds at a speed faster than a satellite towards the NW and suddenly disappeared before hitting the horizon. that was odd as well because we are used to tracking satellites to 30 degrees above the horizon. We were using night vision to track them until they disappeared. A clear night, no wind and no noise was heard.
