Hertzprung-Russel diagram showing the location of SN 2024abfo as determined from the DECam stack images compared to six other Type IIb SNe with progenitor detections: 1993J (Maund et al. 2004), 2008ax (Folatelli et al. 2015), 2011dh (Maund et al. 2011), 2013df (Van Dyk et al. 2014), 2016gkg (Kilpatrick et al. 2022), and 2017gkk (Niu et al. 2024). We show MIST evolutionary tracks for non-rotating, solar-metallicity stars. The faded red marker indicates the effect of AV = 0.3 mag of host-galaxy extinction on the SN 2024abfo progenitor candidate position.
