UFO Sighting in Elk Mountain, Wyoming on October 4th 2015 – Random-Pulsating Light with Direction change

OCT 4th 2015 (maybe the night of the third) While my wife and I were out hunting, camped at Bow River CG, I was telling my her about iridium flashes. Just then a bright flash occurred, SE of Cassiopeia. I said look there's one now. Then it flashed again, brighter. We continued to watch it pulsate at various rates and intensity anywhere from 2 to 6 magnitude. The brighter flashes being the brightest object in the sky. Even at its dimmest, we could still see it at an 8 magnitude. The object, over the course of an hour, made an arch type path. First following a SE path then changing to an easterly path. After the change to an easterly path, it appeared that 4 other objects flew towards it and past. They were of a 7 or 8 magnitude. Like satellites observed orbiting in the night sky. We watched it until it was over the ridge of the mountains. Somewhere around Cetus. I have observed several UFOs in my life, but none like this nor for the length of time. If my wife had not seen it as well, I would have doubted my observation.
