bright circle slowly changing color and slowly moving.I saw something that looked like a star, but it got brighter and as it moved from the north at about a 85° angle from my location to the south where my location was i thought it was a commit. It got closer so i realized that it was a circle. The circle turned neon bright orange and looking in the centre of the circle you could see through it the background of the sky. I looked down, because i was busy with something, but then looked up again and saw it changed color from orange to neon pink/purple, at this time it was almost right above my head. I continued with my work and looked up once again and it was snow white. It moved to the east and faded away as if it was going back from where it came from. Looking at this object it did not seem to move, but everytime i looked up i could tell that it did change it's previous possistion. It did not move fast. It was hard to judge the distance, but it was about the same hight as planes usually fly when you see the whi! te line it leaves,but barely see the plane. I believe you would have been able to fit 2-3 passenger planes in this circle. It was alot bigger than a star and smaller than the moon.The lights it made was not reflection as the sun was setting, but a bright light like a giant neon light. It had no sound, because it was far away.the exact location was about 5 miles south of dimmit texas. Please give comeback on this experience i had.
