Cambridgeshire, England. The conditions were excellent: blue skies, with a few sizable white clouds making an appearance. At around 11:45am, I noticed a single bright "dot" in the sky, almost as high as a satellite would appear at night. No sound was coming from the object. It was moving very slowly. I decided to fetch a pair of 10-zoom binoculars so that I could get a clearer inspection. Through the binoculars, the object appeared oblong-shaped, with luminous sides that alternately glowed then dimmed as it continued to travel slowly along in a strange tumbling-like motion. All the time it maintained its near-satellite altitude. The middle of the oblong-shaped object appeared translucent, and I could see blue sky through it. At no time was the sun reflecting off the object. The object also wasn't a balloon, as it appeared to stop for 20 seconds or so before moving on.
