Scientific paper

We have searched for nearby dwarf galaxies in 27 northern groups with characteristic distances 8-15Mpc based on the Second Palomar Sky Survey prints. In a total area of about 2000 square degrees, we have found 90 low-surface-brightness objects, more than 60% of which are absent from known catalogs and lists. We have classified most of these objects (80%) as irregular dwarf systems. The first 21-cm line observations of the new objects with the 100-m Effelsberg radio telescope showed that the typical linear diameters (1-2kpc), internal motions (30km/s), and hydrogen masses (2x107M{sun}) of the new galaxies correspond to those expected for the dwarf population of nearby groups.
