Abstract
We performed a visual systematic search for galaxies on POSS II(B) plates i n a Milky Way region between l similar or equal to 32 degrees-68 degrees an d b similar or equal to -4 degrees to 19 degrees. This region partly contai ns the Local Void, and the north supergalactic pole exists at the central p art. The surveyed area was about 560 deg(2), and a total of 11,310 galaxies and galaxy candidates with sizes of 0'.1 or greater were identified. Among the detected objects, 152 have been given in galaxy catalogs and 159, incl uding 49 known galaxies, are associated with IRAS point sources. We made a catalog of the detected objects, in which the position in (alpha, delta) an d (l, b), the size, and the features of the image and multiplicity are give n for each object. The surface number densities of the detected objects alm ost depend on the Galactic latitude. In the surveyed region, there is no ne arby cluster and there is an outstanding concentration of galaxies at l = 7 degrees-12 degrees and 4000-5000 km s(-1).
