We revisit the case of SN2002ic that recently revived the debate about theprogenitors of SNeIa after the claim of the unprecedented presence of hydrogenlines over a diluted SNIa spectrum. As an alternative to the previousinterpretation, we suggest that SN2002ic actually was a type Ic SN, the corecollapse of a massive star which lost its hydrogen and helium envelope. In thisscenario the observed interaction with a dense circumstellar material (CSM) isthe predictable consequence of the intense mass-loss of the progenitor and/orof the presence of a gas rich environment. With this view we establish a linkbetween energetic SNeIc and highly interacting SNeIIn and add some credits tothe proposed association of some SNeIIn to GRBs.Comment: Accepted for publication on ApJ
