using the galaxy template subtraction method following the procedures of @roy11. As a galaxy template, we used post-explosion (+600d) images observed on 2011 January 04 under good seeing conditions. Figure \[fig:subimg\] shows an example of this procedure applied to a late-time $V$-band image of . In the template image of 2011 January 04, we can see a clear flux enhancement located approximately 5away (a linear distance of $\sim$ 343pc) from the SN position. This knot is also present in a deep image from the Sloan Digital Sky Survey (SDSS) and it is identified as a   region in the NED catalog. The progenitor of  may have a possible association with this star-forming region. The field of  was calibrated using @landolt09 standard stars of the field SA98 observed on the same night as the SN. A sample of 10 bright and isolated non-variable stars in the field of  was used as local standards to derive the zero points for the SN at each epoch. The location and magnitudes of these local standards are listed in Table \[tab:photstar\]. The entire time span of photometric observation is about 410 days and in Table \[tab:photsn\], we report the $UBVRI$ photometry of the event.
