Red/Yellow orb West of Medford, Oregon, Christmas Eve.On Christmas eve around 7:15, In the sky northwest of Medford Oregon, we saw some kind of flying object. The object was on a west to east track at approximately 6-10K feet. It had a bright red light and glow that would slowly change to yellow then back to red. It did not have running lights or wing beacons. From our observation place, the light was the size and brightness that one would see on top of a cell tower mast about .5 mile away. In the Christmas spirit, we remarked that it could be Rodolph the red nosed reindeer. In reality it was bright enough to hold our attention due to its unique glow. Given its location, in the Medford airspace, we thought it was a private plane at first, or a small remote. We heard no motor or jet. At one point its east bound track paused and then it reversed direction; it did not turn around like an aircraft, it just changed directions and appeared to go up in altitude until it faded away into the heavens.
