H I observations of nearby galaxies - II. The second list of the Karachentsev catalog

We present H I observations of the galaxies in the second list of the Karachentsev catalog of previously 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), V-0 less than or equal to 1500 km s(-1). A total of 78 galaxies have been observed with a detection 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). The Local Void seems to be highly deficient in dwarf galaxies.
