Watching fireworks over northwest boise. large orange orb emanating brighter orange was spotted by me. at least 4 other people saw it. at first i thought it was a chinese lantern but realized it was moving about 100 mph or the speed of a small plane. when it was almost directly overhead light faded but round object was still visible against sky and moving at same speed. i lost it against the nearly full moon but others tracked it another 30 seconds. finally we all had lost sight of it. it was visible for 1 minute glowing then not illuminated for 1 minute approximately.
