We study the local environmental properties of 418 supernovae (SNe) of alltypes using data from the Javalambre Photometric Local Universe Survey(J-PLUS), which includes 5 broad- and 7 narrow-band imaging filters, using twoindependent analyses: 1) the Normalized Cumulative Rank (NCR) method, utilizingall 12 single bands along with five continuum-subtracted narrow-band emissionand absorption bands, and 2) simple stellar population (SSP) synthesis, wherewe build spectral energy distributions (SED) of the surrounding SN environmentusing the 12 filters. Improvements over previous works include: (i) theextension of the NCR technique to other filters using a set of homogeneousdata; (ii) a correction for extinction to all bands based on the relationbetween the g-i color and the color excess; and (iii) a correction for the[NII] line contamination that falls within the H$\alpha$ filter. All NCRdistributions in the broad-band filters, tracing the overall light distributionin each galaxy, are similar to each other, being type Ia, II and IIb SNe arepreferably located in redder environments than the other SN types. The radialdistribution of the SNe shows that type IIb SNe seem to have a preference foroccurring in the inner regions of galaxies. All core-collapse SN (CC) types arestrongly correlated to the [OII] emission, which traces SFR. The NCRdistributions of the Ca II triplet show a clear division between II/IIb/Ia andIb/Ic/IIn subtypes, which is interpreted as a difference in the environmentalmetallicity. Regarding the SSP synthesis, we found that including the 7 J-PLUSnarrow filters in the fitting process has a more significant effect for the CCSN environmental parameters than for SNe Ia, shifting their values towards moreextinct, younger, and more star-forming environments, due to the presence ofstrong emission-lines and stellar absorptions in those narrow-bands.
