Kenta Taguchi (Kyoto University), Miho Kawabata (Kyoto University) report/s a classification of object: SN 2023cr

Type: SN II
Redshift: 0.01368

Remarks: Our spectrum is dominated by a blue continuum. A broad (FWZI ~ 100 A) H beta emission line is seen. H alpha is also seen as an emission line composed of broad (like H beta) and narrow components. Moreover, the He II (4686 A) line was clearly detected. Therefore, we conclude this object is most likely a young SN II. Redshift is from NED.

The following Classification spectrum was provided:
