Three lights the colour of heated steel.I work night shift for a oil feild service company, recording well data. The office air was was getting stuffy and I had stepped out side for a breath of fresh air, and was facing east, when i seen three red lights( the colour of heated metal) moving south,southeast. When i frist seen it, they were in the shape of right angle triangle. the center light was 90 degrees to the other two lights, and they were equal distance from the center light. As they moved a way from me the light on the left appeared to be moving off to the left. After about a minute the lights faded to black (it was like an aperture closing over the light ) and about 1-2 seconds later they disappeared. While they black I could see the outline shapes against the stars untill they dispeared.
