E.E. Barnard and Sherburne Burnham discovered IC 929 in a group around June 1892 with the 36" Lick refractor. Harold Corwin identifies IC 929 with LEDA 2509027, situated 1.2' SSE of Barnard's position. Steinicke identifies 2MASXJ13434549+5538474 (only 30" SE of Barnard's position) as IC 929, but Corwin labels this galaxy as IC 930! Due to Barnard's imprecise positions and the close separations of the galaxies, the identifications are uncertain. See IC 917 for more.

Edwin Hubble catalogued LEDA 2509027 on a plate taken with the 24-inch Yerkes reflector while working on his 1917 PhD thesis "Photographic Investigations of Faint Nebulae" (published in 1920). It was found in his Field IV of nebulae (#48), which included the IC 919 cluster. Hubble didn't assign or suggest an IC designation. The group was also photographed with the Mt Wilson 60" in 1919 and Francis Pease identified LEDA 2509027 as IC 931 in his 1920 paper. Barnard's position for IC 931 is 1' to the SE. So, quite a confusing mess of identifications!

900/1200mm - 48" (5 /9/18): moderately bright, small, round, 15" diameter, stellar nucleus. LEDA 2506714 (assigned to IC 928 by Harold Corwin) is the brightest of 7 galaxies in the core of AGC 1783. IC 926 is 50" W, IC 931 is 50" SE and IC 930 is 45" N! A mag 13.5 star is 0.5' NW.
