    Thank you for your observation, Derek. I have reduced it and stated it in IOD
    format:
    
    29651 06 057A   9999 G 20080218232154500 57 25 0537728-012693 48 S
    
    IOD format: http://www.satobs.org/position/IODformat.html
    
    It was 0.6 s late, and 0.2 deg above the predicted track, relative the elements
    I posted earlier.
    
    Your results are similar to those of the European observers, 4.5 h (3 revs)
    earlier.
