Another faint (~mag 16) supernova with the ALPY 200.

It is identified with high confidence as a type Ia from my spectrum using GELATO

Fantastic! :shock:

I made an approximate statistic from actual CBAT TOCP page (transient magnitude at discover time):

The number of accessible objects greatly increases above mag 15. These excellent performances allow to do a concrete and systematic research.
