S. J. Prentice, K. Maguire, M. R. Magee, P. Clark, K. Skillen (QUB) report/s a classification of object: SN 2018jpw

Type: SN Ia
Redshift: 0.09

Remarks: SNID (Blondin and Tonry 2007, Ap.J. 666, 1024) finds loose matches to SNe Ia a week before and after maximum light with redshifts from 0.09 to 0.1, no particular subtype is favoured. A redshift of 0.075 may be inferred from the spectrum by alignment of common galaxy emission lines and spectroscopic features but they may just be noise. SNID finds no corresponding SN match close to this redshift.

The following Classification spectrum was provided:
