Abstract

We present new Ha 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] × 10^-2 M⊙ yr^-1, and timescale to exhaust the current gas supply of [6, 86] Gyr.
