New and Full Moons, One Thousand and One B.C. to A.D. Sixteen Fifty-One (Memoirs of the American Philosophical Society) (Memoirs of the American Philosophical Society, v. 94)

Reprinted in 1994. This vol. presents tables giving the dates of all new & full moons during an historical era when these data were of considerable interest & importance. To make them more useful the longitudes of the moon at each of these times is also given, as is a consecutive enumeration of the conjunctions & a similar one of the oppositions. All dates are reckoned in the Julian calendar & all times are given in hours & the nearest minute. These dates & times are calculated for an observer in Babylon, or equivalently Baghdad, since this location is fairly centrally located for the historians of the period, exactly 3 hours west of Greenwich. Moreover, the time used is civil time & is based on a 24-hour clock with its origin at midnight; thus noon is 12 hours. Since this vol. may be considered as a supplement to Bryant Tuckerman's tables, all fundamental astronomical elements have been taken from them.
