AbstractWe present the results based on photometric (Swift UVOT), broad-band polarimetric (V and R bands) and optical spectroscopic observations of the Type IIn supernova (SN) 2017hcc. Our study is supplemented with spectropolarimetric data available in literature for this event. The post-peak light-curve evolution is slow (similar to 0.2 mag 100 d(-1) in b band). The spectrum of similar to+27 d shows a blue continuum with narrow emission lines, typical of a Type IIn SN. Archival polarization data along with the Gaia DR2 distances have been utilized to evaluate the interstellar polarization (ISP) towards the SN direction which is found to be P-ISP = 0.17 +/- 0.02 per cent and theta ISP = 140 degrees +/- 3 degrees. To extract the intrinsic polarization of SN 2017hcc, both the observed and the literature polarization measurements were corrected for ISP. We noticed a significant decline of similar to 3.5 per cent (V band) in the intrinsic level of polarization spanning a period of similar to 2 months. In contrast, the intrinsic polarization angles remain nearly constant at all epochs. Our study indicates a substantial variation in the degree of asymmetry in either the ejecta and/or the surrounding medium of SN 2017hcc. We also estimate a mass-loss rate of (M) over dot = 0.12 M-circle dot yr(-1) (for v(w) = 20 km s(-1)) which suggests that the progenitor of SN 2017hcc is most likely a luminous blue variable.
