UFO Sighting in Northglenn, Colorado on 2017-07-04 21:40:00 - Bright light moved quickly straight up then hovered, moved down, changed direction suddenly then disappeared
Sitting in the eastern part of charles c. winburn in northglenn co. across from my condo, watching fireworks, when my girlfriend noticed a red-orange light above a tree to our north, (to our left, above 112th ave) move straight up rapidly. i did not see it ascend, but spotted it the second she pointed it out. i watched as it appeared to hover motionless, for about 10 seconds, before rapidly descending. as it descended, i noticed it change colors, from red, orange, yellow then white. it hovered there for a few seconds, then accelerated to the right (east) rapidly where it momentarily disappeared behind a tree. we saw it again for a brief time as it ascended slightly above the tree that was was blocking our vision. we continued searching the sky for it for it about 5 minutes afterwards, before spotting it once more toward the east. (the direction we faced as we sat) this time it was higher in the sky and was descending rapidly. again i noticed it changing colors as it dropped, until it just flickered out and disappeared. we never saw it again. now i know considering the day of the year, people might want to dismiss our sighting as a mis-identification of fireworks, but we were watching fireworks go off in all directions, and this light didn't act or look like any firework that i have ever seen before.
