While trimming a tree in yard, object appeared directly overhead. i only observed the bottom of the object. it was a disc and had visible structures of concentric rings and spokes coming from the center. the rings and spokes formed segments that were colored gold, silver, and a luminous yellow-like quality that i find especially difficult to describe. it appeared below the clouds and appeared to be quite large, though i had no visual reference with which to compare it. it appeared suddenly, made no sound, made no movements, and disappeared just as suddenly after about 5 seconds. for being so anomalous, my reaction to seeing the object was one of brief puzzlement. i felt no fear or shock. i simply returned to my chore. i thought about it as i worked and considered it a hallucination of some sort. however, i have never hallucinated before and the object had such a quality of being "present" that i found it hard to categorize it as a hallucination. i said nothing of it to anyone and simply thought about it for some time before deciding to make this report.
