AT 2024wpp is the most luminous LFBOT discovered to date. (a) AT 2024wpp in the phase space of peak bolometric luminosity vs. rise time (rest frame) for FBOTs and other transients. Colored (grayscale) stars represent LFBOTs (likely LFBOTs). References: AT 2018cow (R. Margutti et al. 2019; D. A. Perley et al. 2019), CSS 161010 (C. P. Gutiérrez et al. 2024), AT 2018lug (A. Y. Q.

We calculate peak pseudobolometric luminosities of LFBOTs AT 2018lug, AT2020xnd, and AT2020mrf using their peak g-band magnitudes (i.e., ﹩{L}_{{\rm{pk}}}={\nu }_{g}{L}_{{\rm{pk}},{\nu }_{g}}﹩). For FBOTs, SLSNe, and some SNe Ib/c, we similarly plot pseudobolometric luminosities. (b) Comparison of the three best-sampled LFBOTs in the UV (extinction-corrected, host-subtracted absolute magnitudes). For AT 2023fhn, we report the HST results from A. A. Chrimes et al. (2024a) for aperture photometry performed using a 0﹩\mathop{.}\limits^{\unicode{x02033}}﹩4 annulus background and an extinction-corrected Swift w1 observation (see Appendix A for reduction details). Swift UVOT observations of AT 2024wpp captured the rise of an LFBOT and the evolution of an LFBOT at δt ≳ 60 d for the first time at UV wavelengths. (c) AT 2024wpp is ∼4.5 times more UV-luminous than the prototypical event AT 2018cow at peak, and it is the most UV-luminous FBOT discovered to date.
