    20745 1990-071D 1990-071D from the Molniya 1-78 launch looks like one to 
    keep a watch on in this part of the world.
    
    We have a pass around 1807 UTC - very close to Daniel's prediction for 
    decay, and about 90 minutes before that predicted by Calsky.  Space-track 
    prediction can't be passed on owing to the user agreement but certainly does 
    not negate either prediction.  As the 1807 pass is predicted for at this 
    stage to be around  150 km altitude this seems too high for a Molniya decay, 
    but I won't be taking any chances!
    
    Just to add to the interest we have a low ISS/STS pass about 3 minutes 
    later, if the R/B went down on this pass maybe the astronauts might get to 
    see the fireworks!
    
    Visibility looking questionable at this stage, as showers are forecast in 
    the morning followed by fine weather - so highest chance of cloud here is 
    during the time when observation is desirable- *SIGH*
