Supernova 2026aaiv in NGC 7331

Has anybody a spectrum of this Supernova discovered on 01/09/2026?

Yetserday I managed to get hold of the SN 2026aaiv. Below some images before and after meridian flip.
What surprised me is the steep line downwards from 4500Å to 4000Å.

One more from last night 21/09
