Caption: Figure 3.
Light curve of EP240414a in the observer frame in the g (blue), r (green), i (yellow) and z (red) bands. The epochs at which our spectroscopic observations were taken are indicated by the black dashed lines. The r- and i-band light curves show moderate fading within the first day, which we call the first peak. We then see a rebrightening between days 2 and 3 in the g, r, and i bands, which is followed by rapid fading after 4 days in all bands, to which we refer as the second peak. Modest rebrightening in the i band and flattening of the slope in the other bands at ~10 days is observed, consistent with spectroscopic observations of the SN, which is referred to as the third peak.
