SN 1995ah: the first supernova observed in a blue compact dwarf galaxy

We present the properties of the supernova SN 1995ah discovered in a Blue Compact Dwarf galaxy (BCD) around 10 days after the maximum. This is the first supernova event observed in a BCD. The photometric and spectroscopic data suggest that SN1995ah is a Type II supernova and could belong to the rare Bright SNII Linear subclass, for which ~=-18.9+/-0.6 at maximum light.
