    Elevation angle doesn't square with your figures though,

    If it is a satellite, it's a low earth orbit and may vanish into the
    earth's shadow , They do about 1 deg in 15 seconds

    Fast jet maybe,

    for those who know about such things who may well be around. I just saw a bright dot cross about 10 degrees of sky at about 60 degrees of elevation. It did that in less than 5 seconds. That seems too slow and discrete to be a meteorite and too fast to be an orbiting satellite. So must have been an aircraft? With a very bright light.

    Is my logic correct?

    Thanks. That's helpful, you're probably right.

    I thought they had retired those, presumably you meant station.

    I was hoping for a better view of Kosmos 482 but it decided to re-enter elsewhere.

    Which confirmed my object's angular movement was much too fast for that.

    There was nothing on that. But we get a lot of military flights and drone development flights round here that frequently do not switch on civilian transponders.
