Hi All, The accuracy discussion is most interesting. One thing I would like to mention is the personal equation which from my experience is present in all of us. I hark back to the days when four of us would stand together on the bridge to take the noon mer.alt. and it was most interesting to observe that not one of us would come up with the same alt. at dipping time. The result was a compromise depending on the Captain's mood if bad he would use his own which it now can be said was considerably different from the rest and if it persisted showed when making a landfall. At the moment I am busy working on answers to questions I am giving to my students and wonder if anyone is interested in taking on a couple. 1.Find the GMT and LMT of the Moons lower meridian passage on May 20th. 1977 in Lat.72?'N, Long. 22?'E. 2.Find the GMT and LMT of lower meridian passage of the Star Peacock on May 20th. 1977 in Lat.60?'S, Long. 70?'W. Regards to all, Barrie Hudson
