From the Air Almanac is the daily page for July 1, 1992, which is actually printed back to back on one page of the almanac. This shows the P in A table for the moon which changes based on the distance of the moon from the earth on a particular day. Also from the Air almanac are the dip, refraction and coriolis correction tables. > > From H.O. 249 is the page for zero latitude and LHA aries from 180 to 359º for epoch 1980. Also attached are the MOO and MOB tables for 4 and 1 minute periods and the interpolation table for same. The table for correction of precession and nutation is also attached. These provide you with all the information you need to work a three star sight with an assumed latitude of zero, an LHA aries between 180 and 359º on July 1, 1992. --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to NavList@fer3.com To , send email to NavList-@fer3.com -~----------~----~----~----~------~----~------~--~---
