My family was camping at mauthe lake in campbellsport, wi (approx 6-7mi from dundee, wi). we arrived on thurs afternoon and observed nothing out of the ordinary, outside of a racoon attacking our garbage. fri night, 6/22/18, the 3 kids were in the camper watching a movie while my girlfriend and i were out by the fire. my back was to the lake while she was facing it. at approximately 9:40 (derived by text messages and video shot), she exclaimed "what the hell is that?!?". i asked "what" and she replied, "come look". i got out of my chair and observed from her position a large object approx 200-300m from our position out over the lake. orange and spherical in nature. roughly the size of a full moon. the object proceeded to continue in a right to left motion (coming from the west) very slowly at treetop level. at one point hovering in one position. there was no sound associated with the object. after realizing what we were seeing i ran for my phone and started taking video of the object while yelling for the kids to come out and look. both my girlfriend and son recorded video and took pictures in addition to what i took. the object shot off further out, which was the point we began taking video and pictures. it stayed in the sky for roughly 15-20min before disappearing from view. approximately 20-30min later it reappeared in the distance for another 5min.
