Mr Ian David Sharp

Hi all,

It’s been quite a few days since my last update but I have been manfully soldiering on measuring mags with the 3 RBV filters and I’ve barely missed a night!

I was talking to Robin Leadbeater at the excellent BAA Comet Section Meeting yesterday whether he thought that SN 2023ixf was a Type II-L or Type II-P. We both agreed that, since there has been no sign of a plateau to-date, it must be a Type II-L. However, now I’ve added last night’s data all three colours seem to be showing the beginnings of a sharp bend to a flat line (see attached graph – look at the last 2 square points on each line).

I’d be interested in any comments. Maybe the next couple of nights will tell!

Best Regards
