Berliner Astronomisches Jahrbuch

The Berlin Astronomical Yearbook (abbreviated BAJ ) represents almost 200 years is the longest series of publications, which are available in astronomy. In 1960, its contents were - according to an IAU decision - in two internationally published books on year: the Astronomical Ephemeris ( for bodies of the solar system ) and the Apparent Places of Fundamental Stars.

The yearbook was a compendium of data and astrometry of the solar system and had recently a circumference of about 500 pages. It was founded in 1774 by Johann Heinrich Lambert and Johann Elert Bode and appeared from the age group for 1776, edited by Lambert's death in 1777 by Bode alone until 1826. In addition to astronomical tables it contained an extensive appendix in which scientific papers by various authors as well as reports of recent work and discovery messages were printed. So the B.A.J. was an important means of communication of the international astronomical community. After the reorganization by Johann Franz Encke and the reduction of astronomical tables it was published up to and including 1959, and was also the organ, in the 1907, the first globally conceived fundamental catalog was published (see also FK4 1963, FK6 1999/2000).

Since the 1940s it appeared in cooperation with the Heidelberg Yearbook ( Astronomical and Geodetic yearbook ) of the computational Institute in Heidelberg, which also rose in 1959 as other national yearbooks in an international cooperation.

On the path calculations for the planetary ephemeris of the BAJ participated - among other famous astronomers - including the multiple asteroid discoverer Robert Luther, especially from the year 1849 also contributed to the 120 -time asteroid explorer Johann Palisa ( Vienna University Observatory ) at, in 1892 and a star catalog of 1200 fundamental stars from. ten years of observation contributed.
