walked outside at 4:58am on 8/28 looked to the SE and saw object high in the sky. It was stationary and pulsating with the different colors mentioned above. Wife saw it too. Observed object until 5:07 am. for the first 45 minutes could be observed by the naked eye. As the sun rose and the stars started to phase out of the sky object still maintained pulsating action. I'm not sure if it was the brightness of the sun or it moved away from line of sight but couldn't find it after 5:07 am.
