BVri observed light curves (in circles), compared with the multi-scattering dust model of Bulla et al. (2018b) using 1991bg-like SN 2005ke as a reference (black dotted line). Simulated light curves affected by nearby dust with E(B − V) = 0.5 mag at a distance of 1.0 ± 0.5 pc from the SN (blue filled strip) provide very reasonable fits to the observations, while a model in which dust is located at larger distance (100 pc; blue dashed line) just dims the light curves by keeping the same shape.
