    I was wrong. Alan Pickup correctly points out that the objects' designations have been swapped. They were incorrect initially, which
    became obvious once Astra 1K manoeuvred.
    I tried to observe the payload this morning, 2002 Nov 27, shortly after it exited the penumbra, at 10:34:23 UTC, but I did not see
    it. It was to have passed 10 deg above the horizon, nearly 8 deg above Vega.
    About 8 min before the pass, I found Vega just before it vanished behind a cloud, which gave me the approximate azimuth. I tried to
    estimate the correct elevation relative Vega, but I now suspect that I ended up several deg too high, or wandered too close to the
    shadow, or perhaps the object was faint - the phase angle was poor, and it does have some dark surfaces.
    Anyway, I had a sporting chance to make the obs, and it was worth the pain of nearly freezing my fingers in the effort.
