As nightfall fell on Saturday August 29, observers heading out to exploit a dismal night, prior to the early emerging final sector Moon, spotted a shiny addition to the familia r development of Cygnus, excessive overhead from northerly latitudes. This being a time of yr while, relatively at such latitudes, synthetic satellites are usually obvious, many assumed that the second-magnitude interloper, approximately five° north of Deneb, was once simply one other piece of orbiting "junk". in retrospect a couple of minutes later to discover that the thing had now not moved, observers speedy cottoned directly to the truth that this was once no satellite tv for pc.
