Glowing object appears to be luminiscent balloon but dissappears rapidly to the SE at high speed.6:20pm Billings, Montana. Object looked like a ballon caught in the tree. It glowed and seemed to be aluminated by the light of the moon(clear night but only a crescent moon). Object moved across to the other side of the tree. Really looked like a glowing baloon. Object then moved away and actually was not near the tree. Object then appeared to be a more oval shape with a reddish/white light appearance. Object which originally appeared to be just above the ground then moved upward to the east and seemed to reach an altitude of several thousand feet, like an airliner. The object then moved fast towards the east at what appeared to be the same altitude of a commercial jet, however, there was no sound at all. The object dissappeared to the SE.
