HI observations of nearby galaxies - I. The first list of the Karachentsev catalog

We present H i observations of the galaxies in the second list of the Karachentsev catalog of pre- viously unknown nearby dwarf galaxies (Karachentseva et al. 1999). This survey covers an area of 6000 square degrees within the boundaries RA (14h, 23h30) and Dec. ( 20 0 ,+ 60 0 ) including the nearest cosmic void: RA = 18 h 38 m , Dec. = +18 0 , V0 1500 km s 1 .A total of 78 galaxies have been observed with a de- tection rate of 42%. We searched a frequency band corresponding to heliocentric radial velocities from 470 km s 1 to +3970 km s 1 . Non-detections are either due to limited coverage in radial velocity, confusion with Local H i (mainly in the velocity range 140 km s 1 to +20 km s 1 ), or lack of sensitivity for very weak emission. In the general direction toward the Local Void we detected only one galaxy with a corrected radial velocity below 1500 km s 1 .T heLocal Void seems to be
