2000A&AS..141..469H HI observations of nearby galaxies. I. The first list of the Karachentsev catalog. HUCHTMEIER W.K., KARACHENTSEV I.D., KARACHENTSEVA V.E., EHLE M. Received september 14, accepted November 16, 1999 Abstract: We present HI observations of the galaxies in the first list of the Karachentsev catalog of previously unknown nearby dwarf galaxies (Karachentseva & Karachentsev 1998). This survey covers all known nearby galaxy groups within the Local Volume (i.e. within 10Mpc) and their environment, that is about 25% of the total sky. A total of 257 galaxies have been observed with a detection rate of 60%. We searched a frequency band corresponding to heliocentric radial velocities from -470 km s^-1^ to ~+4000km s^-1^. Non-detections are either due to limited coverage in radial velocity, confusion with Local HI (mainly in the velocity range -140km s^- 1^ to +20 km s^-1^), or lack of sensitivity for very weak emission. 25% of the detected galaxies are located within the Local Volume. Those galaxies are dwarf galaxies judged by their optical linear diameter (1.4+/-0.2kpc on the average), their mean total HI mass (4.6x10^7^M_sun_), and their observed linewidths (39km s^-1^). Key words: galaxies: distances and redshifts; dwarf; fundamental parameters; general
