Classification spectrum for SN2017igf (in black) recorded Saturday night at mag 15.8 with the ALPY 200 just 12 hours after it was discovered by the ASAS-SN survey, which brings my classification total into double figures.
It is clearly a type Ia (SNID classification program best match in red) but SNID predicts it to be near maximum from the explosion velocity (calculated from blue shift of the Silicon absorption, taking into account the host redshift) which would mean it has a low absolute luminosity. If it is normal, it should get significantly brighter over the next few days. One to watch !
