Absolute magnitude at peak vs. the duration of transients above half-peak magnitude updated from D. A. Perley et al. (2020). For the background we show different SNe and TDEs from the Zwicky Transient Facility (ZTF) bright transient sample, as well as the set of fast transients identified by A. Y. Q. Ho et al. (2023). We note there is a clear observational selection against objects that lie toward the short-duration (≲2 days) region because of the cadences of current surveys. We mark the approximate locations of the optical/IR light of EP240414a for each of the three peaks we identify from the light curve (where the duration and absolute magnitude of the first peak is most uncertain), demonstrating how it compares to the most luminous and fast optical transients observed to date. The implication is that some fast optical transients may arise from similar events to EP240414a, but the initial X-ray outburst was missed.
