Camping trip on a perfectly clear evening at the lake. There is absolute pitch dark except for stars in sky and a tiny crescent moon on the lower horizon.We are around the campfire sky-watching and my 9 yr old son sees what he thought was a plane originally until the light takes on a zig-zag path then north, then south, back & forth over the sky.Husband grabs binoculars and all 3 of us witnessed a glowing, multi/overlapping spherical thing is best way to describe.Shape reminds me of that Spirograph toy thing when I was a kid.It's like pulsating,almost like it's breathing and there's this black hole-like thing within that appears to expand & contract.The sphere seems to dim when the hole thing is expanding and lights are more bright and vivid when hole becomes small. It moves overhead,way up high, back & forth,side to side and we observe this for nearly an hour as it seems to go higher & higher until it damn well looks like a star and then stations itself in a permanent place in the South sky - camouflaged just blending in with the rest of the stars!I watched and kept eye through the binoculars and could still make out the glowing spherical part of it to tell it apart from the other stars in the sky.My son said he started to feel 'weird' but I mostly think he was somewhat amazed & freaked out about the idea of potential aliens overhead.I am a licensed psychotherapist in Great Falls, MT and believe me this is what we all saw. Pretty incredible and wish I could draw you a picture of the glowing,spherical thing that night.
