2005A&A...434..935K H{alpha} imaging of the local volume galaxies I. The NGC 6946 galaxy group I. D. Karachentsev, S. S. Kajsin, Z. Tsvetanov and H. Ford Received 11 January 2005 / Accepted 11 February 2005 We present new H{alpha} 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_sun_/L_sun_, current star formation activity of [0.2, ~5.2] x 10^-2^ ~M_sun_ yr^-1^, and timescale to exhaust the current gas supply of [6, 86] Gyr. Keywords: galaxies: dwarf, stars: formation
