2 seperate sets of flashing lights in a triagle formation.On 1 Sept. 2007, at approx 23:30 my wife and I were at the Redwood drive-in seeing a movie. During the intermission I went to the restroom and when I came back my wife was in the bed of the truck looking at something in the sky. She asked me where the binoculars are and I got them for her. She was looking at a bright light in the south/western sky that started to emit red, yellow and bluish/green lights to a smaller light. It then appeared to turn and do the same to yet another smaller light across from the 1st one (the 3 of them together made what appeared to be a perfect triangle) it appeared to change shapes as it was turning. At one point it looked like a diamond and then went into a circle. After which, the 1st smaller light flashed back to the brighter light as did the 2nd smaller light. We watched this for about 30-45 minutes. We decided to drive out west to see if we could still see it. As we drove along I-80 west we could see the brighter light the whole time. About the time we got to the Grantsville area it began to fade in and out disappearing and reappearing in about 2 minute intervals. This happened 3-4 times we pulled off of exit 77 and drove south for about 3 miles and watched the same thing. After about 20 minutes I was looking at the North and saw 3 more lights doing the same thing again with the brightest one on top of 2 smaller ones on either side making a perfect triangle. We watched both sets for about 20 minutes repeating their flashing back and forth until it began to get to cloudy and we then drove home.((NUFORC Note: The planet, Jupiter, is in the southwest sky. We suspect that the witnesses may have been viewing celestial bodies. PD))
