Abstract

Based on film copies of the POSS-II we inspected a wide area of □° in the direction of the nearest cosmic void: {RA = 18^h 38^m, , 1500 km s^-1}. As a result we present a list of 78 nearby dwarf galaxy candidates which have angular diameters and a mean surface brightness , mag/□″. Of them 22 are in the direction of the Local Void region. To measure their redshifts, a HI survey of these objects is undertaken on the 100 m Effelsberg telescope.
