We find a distance of 4.6 +/- 0.7 Mpc, or a true distance modulus (m - M)_0_ = 28.31 +/- 0.30. This implies an absolute magnitude at maximum of M_B_ = - 19.90 +/- 0.35 for the extensively studied type Ia supernova SN1972E in NGC 5253.STAMPAenThe distance to NGC 5253 and the absolute magnitude at maximum of SN 1972EArticlehttps://ui.adsabs.harvard.edu/abs/1992A%26A...257L...1D/abstract1992A&A...257L...1DFIS/05 - ASTRONOMIA E ASTROFISICA
