Abstract
Long-slit observations of 4 dwarf spheroidal galaxies in the M 81 group are presented. We have obtained the heliocentric velocity of a globular cluste r candidate located near the center of DDO 78 to be 55 +/- 10 km s(-1) by c ross-correlation with template stars. We estimated a heliocentric radial ve locity of -116 +/- 21 km s(-1) for an HII region seen in K 61. A red diffus e object near the K 64 center is found to be a remote galaxy with a helioce ntric velocity of +46 530 km s(-1).
