Western Nebraska white-blue round lightWe noticed a white, round light with a blueish outerglow in the Northeast sky at approx. 2 o'clock on a North arrow. It lasted for a duration of 1½ - 2½ minutes descending appoximately 50 degrees in the sky. The light dimmed after descending 40 degrees then brightened briefly and then dimmmed out completely. The line of sight was unobstructed by any trees or clouds in the sky. There was a tree to the left of the object that we were able to tract how far the light was descending. There was no sound. The light was 10 times bigger than any other star in the sky. We were standing underneath a street light and quite shocked when we noticed the unusual behavior of the light. We then blocked the street light out of our vision with our hands and noticed the other stars in the sky. It was not a plane or satellite as first two osbervers have seen both on numerous occassions in the night sky. The third and fourth observers only viewed the light for the last 20-30 seconds to watch it descend, dim and disappear.
