Abstract: Linkage between core-collapse supernovae (SNe) and their progenitors is not fully understood and ongoing effort of searching and identifying the progenitors is needed. $mathrm{SN,2024abfl}$ is a recent Type II supernova exploded in the nearby star-bursting galaxy $mathrm{NGC,2146}$, which is also the host galaxy of $mathrm{SN,2018zd}$. From archival Hubble Space Telescope (HST) data, we have found a red source ($mathrm{m_{F814W} sim 25}$) near the location (angular distance $leq 0.2″$) of $mathrm{SN,2024abfl}$ before its explosion. With F814W and F606W photometry, we found that the properties of this source matched a typical red supergiant (RSG) moderately reddened by interstellar dust at the distance of the host galaxy. We conclude that the $mathrm{SN,2024abfl}$ had an RSG progenitor with initial mass of $mathrm{10M_{odot}}$–$mathrm{16,M_{odot}}$.arXiv:2412.13166v1 Announce Type: new
