Open, JC BVRI, Sloan ugriz, ATLAS c, o and NIR JHK light curves (left) over the one-year follow-up of SN 2018ivc. The graph has been broken into two windows (before and after +3 months) for clarity. Downward triangles mark upper limits. B − V and V − R reddening-corrected colour curves (right) of SN 2018ivc (filled points) and of the comparison objects: SNe 1993J, 2001fa, 2007fz, 1996al, and 1998S. For SN 2018ivc, we considered both the low (orange circles) and high (blue diamonds) reddening scenarios (see Sect. 4.4).
