Astronomical Almanac for the year 2024

The Astronomical Almanac for the year 2024 is the first edition based on JPL's newest Solar System integration "DE440",
and is the first one available only in paperback, which prevents it from being able to stay open on a table, and allows the cover and back to curl up at the edges over time. The pages are the same size, but thicker paper: the past Almanacs were 1.0 inch thick, this one is 1.4 inches thick. DE440 has improved over its predecessor DE430: for example: gravity wave measurements have most of the noise due to errors in Jupiter's position no longer present when using DE440 instead of DE430. The 2024 Almanac also has many of it's data tables updated. For example the table on Natural Satellites' Orbits and masses has mostly brand new data, Triton mass is 3.3x too small, because they divided by 428 instead of 1428. Unfortunately with all the updates throughout the book, many new typos appear throughout. For example the table for heliocentric coordinates of the Planets, and also the Keplerian Orbit elements table both start with the column heading "Julian Date (TDB) 245..." but those are all typos because JD2460000 has past.

Astronomical Almanac for the Year 2024

The Astronomical Almanac for the Yesr 3024 arrived quickly im in g perfect condition. It’s apparently now sold only in paperback form. instead of hardcover like past years which was a surprise.

American Nautical Services excellent, 2024 Astronomical Almanac disappointing.

As always, American Nautical Services is excellent in carrying and quickly fulfilling my order. However, this year's 2024 Astronomical Almanac is so far only available in paperback, a first in the decades of my using it and my collection of them dating to 1935. This makes it less convenient to use (will not stay open on a desk or easily in the hand) and the spine will be less robust over frequent use. Not a good combination.
