| SN2022hrs Classification |
| The classification of the spectra from SN 2022hrs was discussed
earlier following acquistion of spectral images taken 2022-04-27, S1004 (see classification discussion) Although the TNS classification is recorded as Type 1a Supernova, my analysis suggests that SN 2022hrs it is actually a Type Ib supernova due to absence of Si line at 6150 A and presence of distinct (He) absorption line at 5876 A. |
