    Notes:
    ---------
    
    (1) Earlier part of evening clouded out- cleared just as suddenly as it
        clouded over earlier
    
    (2) Unknown geostationary #91096 found whilst looking at Inmarsat 3F1.
        Could see in "real time" on the monitor giving short brightish 
    flashes.
    
    (3) Progress with the 6 inch f/5 reflector is slow - a "try-out" on
        22nd feb was a flop with too much vibration and other mechanical
        problems. The telescope pier has now been replaced by a steel pole
        buried in concrete - will continue work on it tomorrow.
    
    (4) SL 12 R/B 91046D #21536 predicted close to where 90053 was found.
        Only one object seen - think I have correctly identified it as #90053.
    
    Cheers
