A Survey for Low Surface Brightness Dwarf

By applying a digital ltering technique to 1550 deg 2 of the POSS-II in the vicinity of M31, we found two previously unidentiied very low surface brightness dwarf galaxies which we designate And V and VI. Follow-up imaging with the KPNO 4-m telescope resolved these into stars easily. The V-and I-band images of And V indicate a distance similar to that of M31, and {1.5. All evidence strongly supports its classiication as a dwarf spheroidal companion to M31. Data for And VI are being analyzed, but preliminary indications support a similar conclusion. Our search for more dwarfs, including follow-up observations of numerous candidates found via digital ltering, is incomplete; thus, further identiications may be forthcoming.
