3406 Omsk is a main-belt asteroid discovered on February 21, 1969 by the Russian astronomer Bella Burnasheva at the Crimean Astrophysical Observatory, and given a preliminary designation of 1969 DA. It was named for the discoverer's birthplace of Omsk, the administrative center of the Omsk Oblast in Russia.[3]
Photometric observations of this asteroid made in 2007 at the Mt. Tarana Observatory in Bathurst, Australia were used to produce a light curve that showed a period of 7.275 ± 0.006 hours with a brightness variation of 0.28 in magnitude. This indicates a ratio of 1.3 between the lengths of the major and minor axes.[2]
