Abstract (from CDS):

We present new Hα imaging of all known dwarf irregular companions to NGC 6946: UGC 11583, KK 251, KK 252, KKR 55, KKR 56, Cepheus 1, KKR 59, and KKR 60. The galaxies span a range of blue absolute magnitudes of [-13.6, -17.6], relative gas content of [0.1, 2.5]M_☉/L_☉, current star formation activity of [0.2, 5.2]x10^–2M_☉/yr, and timescale to exhaust the current gas supply of [6, 86]Gyr.
