Results of the Local Group Dwarf Hunt

Abstract

We will present the results from an all-sky search for new members of the Local Group, based on survey plates (POSS-II and ESO/SRC). After two early discoveries (Antlia and Cetus) no previously unknown members were found. We estimate that at most one remains undiscovered in the accessible region of the sky brighter than about 24-25 magnitudes per square arc second, and that about 6-8 might be hiding behind the Milky Way.
