Went outside to goodbye friends. looked up as there was a bright--seemingly burning object stationary straight up from zip 85375. first thought it was a hot air balloon flying in the dark, creating a big glow. the object was stationary and seemed to be "fireball like". it then moved toward the sw and ascended over the cloud cover until it was out of sight. was very curious--went into the house to get my nikon bino's but could get no better clarity on the object. witnesses include a senior retired usaf officer and a retired airline pilot plus one other adult.
