Using a Tully-Fisher distance modulus to the host galaxy, MGC -02-11-023, of 35.69 mag (Theureau et al., 2007, A&A, 465, 71) and correcting for Milky Way extinction, the current absolute magnitude is M_r = -16.8 mag and rising. This is at the low end of the peak luminosity distribution of SNe IIn and the H-alpha line is relatively narrow, perhaps indicating that AT2021aapa is a non-terminal LBV eruption 2021TNSCR3592....1D
