    Hi Stan,
    
    > Is this the method discussed in the Navigator's Newsletter Issue 4?
    
    I don't think so---the author seems to be talking about altitude
    observations of the moon (together with star LOPs) to estimate the
    clock error, a la Chichester.
    
    I've been fooling around in Stellarium using its angle-measurement
    tool, and it seems to be fairly easy to find bright star pairs that
    are close to a star-Moon distance at any given time.  Could even do
    this all experimentally, without elaborate precomputation---just go
    outside, sight the desired star-Moon pair, then keep that sextant
    setting and search for star-star pairs nearly equal in angle by
    sweeping the sextant.
    
    Cheers,
    Peter
