Single object approached from the N-NW, Twinkled, sometimes emited red-blue-gold flashes, made 90deg. turn then hovered for 20 min.Object approached from the N-NW twinkled sometimes with red green or gold color. Comercial airplanes do not approach from this direction. Object moved towards the south/SE and made an abrupt 90 deg turn upward. Object apared to stop and hover. Ligh intensity did not deminish over 20 min of observation. Object appeared to hover but shift slightly in its position. As a comercial aircraft decended to the airport, object seemed to "bob" in the wake of the plane, but it also did not seem to be relativly near the plane, perhaps this was just light defraction. Object appeared to hover over the campus of WSU, but could have been much further away. There was only one object, shape unknown. I am a research technician at Washington State University, I am 35 years old, maried, and I have never seen anything like this. At first I thought the object was a military aircraft, or helicopter, but after it hovered for 20 min, I was certain it was no airplane. The next morning the University network was not functioning in the AM..perhaps unrelated.
