Object was not a weather balloon, or any known aircraft.Watched this object before it got dark, it was a dirty white color. It stayed stationary in the sky. When the sun began to set, it lit up in a bright white light. After a good 45 minutes, all the time stationary, it changed colors from white, to a mixture of white and red, with like a red aura around it. Not long after that, it began moving rapidly up at an angle, until it looked like a star in the sky, then disappeared. No flashing beacon. The object was big! Got poor pictures from a cell phone camera, but there was a man taking pictures with a 35mm camera with a big zoom lens. Many people witnessed this object.
