Tried observing with an 8" around 04:00 UT on 9 Sep 99. Range was around 40300 km and magnitude 11.3 objects would have been relatively easy to detect...fainter objects to about 12 likely with averted vision. Using the following elsets (the later from OIG) I was unable to see Chandra.

Of course it is possible the satellite was in an attitude making it too faint to see. Ron Lee
