I made a recent observation of this object (14/Oct/99, 18:51UT) timing 50
periods. It had unevenly spaced alterate flashes (6.4s+7.4s = 13.8s, the
mean flash period was 6.84s. This is fairly similar to Jim's timing,
supporting the conclusion that this was the Centaur he observed.

Further general information, including flash periods of Centaur rockets can
be found on my web page;


Best wishes & clear skies.
