This is more of a surveying problem rather than a marine navigation problem, and primarily of historical interest, but.... All the ephemerides I have seen for occultations of Jupiter's moons are timed to the minute. I have not seen tables for occultation of stars by the moon. Was one minute the limit of resolution for determining GMT in the old days or could averaging of numerous observations give a more accurate determination of Greenwich time? Thanks, Fred
