ApJ, 666, 1024), on our SALT/RSS spectra, we confirm the classification of SN 2022acko as a young type II. Best matches point to a type IIP few days before peak, with clear hydrogen features. We also remark an emission feature around 4600 Angstroms, which is associated with Flash features. 2022TNSCR3548....1M
