About this image

A spectrum of Supernova SN 2023vyl in ngc7625 measured using the ALPY 200 at maximum brightness (black) compared with a best fit from GELATO (blue).

It was discovered by ATLAS and classified spectroscopically as a type 1a by amateur Claudio Balcon (also confirmed by this spectrum). With a host galaxy distance modulus of 32.5 it had the potential to reach mag 13 but fell short, (g 15.7, r 14.5 ZTF) possibly due to interstellar extinction in the host galaxy

As an added bonus some light from the host galaxy was also caught in the spectrograph slit, with the spectrum showing strong H alpha emission. NGC7625 is catalogued in SIMBAD as an active galaxy nucleus candidate, though as can be seen from the spectrograph guider image, the region sampled here is offset from the galactic nucleus. (Images showing HII active regions and dust can be found here)
