S. J. Prentice (QUB) report/s a classification of object: SN 2018hmn

Type: SN Ia-91T-like
Redshift: 0.043

Remarks: Using SNID (Blondin and Tonry 2007, Ap.J. 666, 1024), I find a good match to 91T-like SN 1999aa at z = 0.043 around 26 days after maximum light. Other plausible matches include normal SNe Ia at a similar phase but lower redshift (z ~ 0.026). SN 1999aa provides the best match to the features between 6100 and 6500 Angstroms (observed).
