An optically directed HI search for new dwarf members of the M 81 group

We present a search for neutral hydrogen (HI) emission from optically identified dwarf galaxy candidates in the larger M 81 group area. Of 136 candidates, 68 galaxies have been detected (this corresponds to a detection rate of ~ 49%). Most of the detected galaxies are background objects and fail to be classified as dwarfs. Many known dwarfs in the M 81 group have been detected, but no new members have been discovered.
