Large multicolored disk radiating many colors w/ long hanging arms hovering over an hour above Griffin/Sterling Creek area.~150'+ wide x 30' tall disk w/ dome in center, top and bottom. The glowing/flashing colors seemed to originate from the bottom dome, radiating out from the center to the rim of the disk and around its circumference. Along the disks edge it only showed as blue/green were as the center blurred all colors of the rainbow. Long 100' arms hung below and in front, curling and extending, moving like long worms and coiling like a snake, only visible by the radiating lights from the bottom of the disk.It mostly sat over the Griffin/Sterling Creek area and no higher than Anderson Butte (~1/2 mile+ elevation above valley floor).When it moved, it didn't seem like it was moving, but would suddenly appear closer/farther. Would occasionally wobble on its axis, giving a better view of the disk's full shape. Eventually drifted low and closer to the mountains, out of my view.Woke up my mother to witness. When both of our eyes had adjust well to the lighting, we both could clearly make out the legs/arms extending out from the bottom/center of the disk. Also, awoke two friends by phone who both watched from their houses. Confirming location, movement, size, color, duration. But angles, light, fatigue and eye sight caused my mother and I to have the best view.The legs are still freaking me out.
