Bright yellow-orange light that morphed into two, then one, then faded in and out before disappearing.Saw my second UFO in a month last night (5/6/99). Interestingly enough, I had a "feeling" about it before it happened. The incident occurred while we were driving home from a shopping foray into Pueblo, CO. A little after sunset I spotted another yellow-orange light, this time in the Western sky, though not as bright as the prior UFO. It was stationary and I thought it might be a star but then it split into TWO lights right next to each other, then merged back into one, then two--the strangest thing. After a couple of minutes of shape-shifting, it started fading in and out. It would disappear for 30-40 seconds, then appear again. This occurred MULTIPLE times and there were ZERO clouds in the sky that could have caused the light to be periodically obscured. Also it was not a mechanical strobing like airplane lights but more random and the source wasn't moving much. Finally, after another 3-4 minutes, it just faded out for good. My wife saw it too, although she couldn't get as sustained a look because she was driving when it occurred.
