Mentor 6 is a large reconnaissance satellite located in a geostationary orbit somewhere over the Indian Ocean where it probably monitors nefarious goings on in the Middle East and elsewhere. It is large, probably the size of a football pitch. Being located in this position, certain stars appear to pass it every day, notably Omicron Ceti and V Aquilae. As a result of observing these stars, when they are in the right position, Mentor 6 appears in the field. However diurnal rotation carries the stars out of the field very quickly. Two other geostationary satellites have been recorded in the original image. If a longer exposure was used, the stars would have trailed, but Mentor 6 would have remained as a stellar point image.
