12619 Anubelshunu           Discovered 1960 Sept. 24 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Anu Belshunu (249 B.C.-c. 185 B.C.) was lamentation priest and interpreter of the astrological omen series Enuma Anu Enlil at the Temple of Anu in Uruk. A collection of astrological cuneiform tablets from his library contains some of the earliest realistic depictions of the Babylonian constellations.
