Top and bottom: the hosts of SN 2007kk (UGC 2828) and SN 2005L (MCG+07-33-005), respectively, both classified as globally star-forming (Childress et al. 2013b). Left: color images made using observations from SNIFS and SDSS-III (Aihara et al. 2011). On both images, the field-of-view of SNIFS, centered on the SN position (white-star marker), is indicated by the orange central square. Right: Hα surface brightness maps of the SN vicinities (the generation of these maps is detailed in Sect. 2.3). SN 2007kk occurred in a passive environment more than 1.5 kpc from the closest star-forming region, while SN 2005L is located at the edge of such a region.
