Isis 1 not a match

Hi Rainer,

I checked your identification of Isis 1 (primarily to see why it
didn't pop out during my search for Magnus's UNID):

This satellite did indeed make a very high southbound pass
(for all intents and purposes, directly overhead) at 16:52 UTC.
However, it was never less than 10 degrees away from Alderamin
(which was at 72-deg elevation in the northwest), so I ruled it out.
The two sats I identified earlier (C2058 and Nadezhda 3r) were
the only ones to come within 10 degrees of the star, with
southbound headings, within 3 minutes of his reported time.  --R
