    Notes:
    -------
    
    (1) Much cloud eventually forcing me to abandon trying.
    
    (2) Trying out new method of measuring - slower to do but should be
        considerably more accurate.
    
    (3) Expect to have my new camera early next week but sure to be cloudy
        every night for a long time afterwards as a result of this!
    
    Cheers
    Greg
