Yes that was a good result on SN2018gj at mag 14.5 by Etienne Bertrand using a standard ALPY. I see there is now a professional confirmation of type II too

Looking at the weather forecast my next clear spell is likely be Saturday evening when I am down at Burlington House talking about…. supernova spectroscopy ! If it had been a type Ia it would probably have got pretty bright, perhaps mag 12 but as a type II, maximum will be less certain and probably lower.
