Abstract: At the instant of midnight of New Year’s Eve on the Greenwich meridian, or when the mean sun is at the 180th meridian, American navigators on the seven seas will commence using a new type Nautical Almanac. It is well for those concerned not to neglect gaining some acquaintance with the new almanac before it becomes necessary to use it. Navigators aboard ship along the western coast of South America and on the Indian Ocean will be the first to use the new type almanac. Those on the west coast of South America will need it for evening sights December 31, 1949, and those in the Indian Ocean will use it for morning sights January 1, 1950. It is easily possible that both the present and the new type almanacs will have to be used for calculating a round of sights; some observations being made a short time before and some shortly after the instant of Greenwich midnight.
