Caption: Figure 2.

Multiband photometry of SN 2024iss. The left panel shows the first peak from shock breakout and cooling, while the right panel shows the full light curve. The downward triangle points are the last ZTF g-band nondetection upper limits at 0.027 day before first light. All data points are corrected for Milky Way and host-galaxy extinction.
