Radial Velocities of Dwarf Spheroidal Galaxies in the M81 Group

Long-slit observations of 4 dwarf spheroidal galaxies in the M81 group are presented. We have obtained a heliocentric velocity of globular cluster candidate located near the center of DDO78 to be +55 ± 10 km/s by cross-correlation with template stars. We estimated a heliocentric radial velocity of -116 ± 21 km/s for an HII region seen in the K 61. A red diffuse object near the K64 center is found to be a remote galaxy with a heliocentric velocity of +46530 km/s.
