disc shaped orange in color with darker crater shapes with in it

I had seen this ufo when I was ten yrs old, and living at Austin ave and Barry streets in Chicago. I happened to look up in the sky and saw this disc moving north. This disc was orange in color like the moon at certain times and had dark circles with in it, almost looking like craters on the moon and it did not have a tail like those of comets. I can't say how far up in the sky it was but it seemed to be moving rather slowly, maybe twenty to thirty miles per hour, because I watched it for a minute or two as it moved across the sky. I was only ten but I know what I saw and will never forget it. I wish that I could be hypnotized and draw a picture of it because like I said I will never forget what I saw that night.
Witness indicates that the date of the sighting is approximate.  PD
