A bright star like object 1/10 diameter of the moon, appeared stationery but moved over a half hour period then disappeared.The object looked like a planet (seen through a 250mm camera zoom lens) - (unfortunately didn't photograph it!) - about 1/10th the diameter of the moon and slightly above and fairly well to the right of the moon (approx. 5 degrees)in a sunlit evening sky. We thought it was Venus at first, though much brighter and larger than we would usually expect. It appeared to have a shadow much like the moon had hence our conclusion that it must be a planet. It also appeared to be stationary. However half an hour later when we next looked it had moved to a postion over the moon, more than the moon would have moved in that time and was no longer on the circle line that conjoins the planets and the moon. The sun was setting at the time and a couple of minutes later when we next looked the "star" had almost disappeared as if it was going into the earth's shadow and disappeared entirely in the next couple of minutes. Implying that the object was far closer than a planet or the moon.
