American Astronomical Almanac for the Year 2022

This joint publication of the U.S. Naval Observatory and H M. Hydrographic Office (England), once easily obtainable from the U.S. Government Printing Office, has become very hard to get in the last few years. The GPO's erratic publication schedule and short production runs have resulted in reduced obtainability. Some suppliers offer it on Amazon at prices as high as $100, but for the last two years American Nautical Supply has been a reliable source at publisher's prices ($65 in 2022). American Nautical Supply's incredibly friendly and helpful staff have stocked an adequate supply when I've needed help and are a pleasure to deal with.
Formerly known as The American Ephemeris and Nautical Almanac (AENA), this book has maintained its fine features with improvements. The handsome 10 1/4 by 7 1/4 inch volume is bound in blue cloth (hard-back) and lists traditional tables of astrometric and astronomical data for the solar system's Sun, planets and moons, all helpful for professional and amateur astronomers. Tables of bright stars for land surveying and celestial nav (got GPS? You should still carry backup celestial equipment), astronomical radio sources and quasars, and spectral data on hundreds of stars are presented in well-designed tables. Graphic positions of planetary moons are indispensable to amateur astronomers, as are tables of lunar positions, particularly selenographic colongitude (must be calculated from selenographic longitude of the Sun otherwise). Most of the material is public domain except for parts written by the English authors (mostly graphic diagrams of lunar and solar eclipses), which are copyright H.;M. Hydrographic Office. The pages are numbered 1 to N for each lettered section; this seemed awkward at first, but it makes for easy location of particular areas of interest. The hundreds of pages of notes and explanations (sections B K, L, and M, plus introductory material in other sections) provide a deep education into the mysteries of astronomical data, especially the section explaining time scales, a confusing and difficult topic. My only complaint, a small one, is that for most tables, values are given for Terrestrial Time, and users should be careful to note the kind of time for the table in use. Terrestrial Time and Coordinaed Universal Time (civil and military time-services are mostly UTC). TT is fine for those calculating future positions of celestial objects, but other users, particularly occultation observers, should remember that TT and UTC differ by about 70 seconds. Most of the book is accessible to users without algebra or trigonometry, but these help to get maximum use of all parts of the book. [Washington, D.C. and London, U.K, ISBN 978-0-7077-46203.]
