Very large and very bright light in the SSE sky over the Mountain Range.I was driving home around 11:15pm from Missoula to Florence, as I turned onto Old HWY 93 I noticed a very large bright light in the sky. The direction was roughly SSE of Florence and I would guess about eleven miles from HWY 93. It was bright yellow and hovering over the first saddle of the Mountian range when I saw it. I know that there isn't a radio tower that has that strong of a light, and I can't say that I have ever seen a radio tower over that direction. The light stayed stationary until I reached the county line and then it was lost behind some trees. When I past the trees the light was gone...not a trace.
