Optical light curves of SN 2024iss. Left panel: Early-time multiband photometry within the first ten days. Right panel: Multiband light curves of SN 2024iss within the first ∼100 days. All magnitudes are corrected for the Galactic extinction. For better clarity, light curves in different bandpasses were shifted vertically by arbitrary numbers as labeled on the right. Facilities used to obtain the photometry are indicated by the legend. The last nondetection from ASAS-SN is marked by the green inverted triangle.
