R. Cartier, J. Espinoza (CTIO), C. Contreras (STScI), A. Boltom (NOAO), C. Inserra (Southampton), E. Kankare (QUB), K. Maguire ( report/s a classification of object: SN 2018ebx

Type: SN Ia
Redshift: 0.034

Remarks: From the host galaxy narrow emission lines we measured a redshift of 0.034, but the best fit templates are of SNe Ia at z~0.027 at one week past maximum. The SN seems to be peculiar, because ASAS-SN reported V = 16.50 mag on 2018-07-21 and g=17.3 mag on 2018-07-22, suggesting an intrinsic red colour or a fast decline in the SN brightness. The classification spectrum does not look peculiarly red, suggesting a fast photometric evolution rather than red colours. We encourage photometric follow-up.

The following Classification spectrum was provided:
