    I have appended tonight's ground tracks of Raduga 33's passages through perigee,
    when it may glow due to atmospheric heating.
    
    Perigee passages occur near latitude 47.9 deg. Observers within about 4.6 deg
    above and below that latitude, located along the longitude track, may see
    perigee at maximum elevations of at least 10 deg.
    
    The object will be within Earth's shadow, so it will only be visible if it is
    glowing due to atmospheric heating. There is no guarantee, but I believe there
    is a sporting chance.
    
    When running predictions for your site, make certain to command your ephemeris
    generator to show passes within the shadow.
    
    Predictions can easily be off by 10 min or more, so be prepared to look early
    and late.
    
    Keep in mind that the predicted path will change depending on how early/late the
    object is, due to Earth's rotation. This is especially important if you are
    expecting a high elevation pass. 
    
    My pass, predicted for 2004 May 03 at 05:15 UTC, will reach only 11 deg - low
    enough that the track will be little affected by prediction errors of +/- 10
    min. On such a low pass, I will use binoculars.
    
    The object is so low at perigee, that you are far more likely to have a low
    pass, than a high one, but it is still worth a try. Low passes require a bit
    more planning, to make certain you have an unobstructed view. Also, try to
    intercept the satellite where its track passes some reasonably bright stars, say
    mag 4 or brighter. Bright stars are easier to find when looking through the murk
    at 10 deg elevation.
    
    I will be unavailable to post updates until 0 h UTC, perhaps later.
