SN 2023ixf in M101 Mag is rapidly dropping again!

[Mr Ian David Sharp]

Hi all,

I’m still measuring the brightness of SN 2023ixf as regularly as I can in R, V and B filters. It has been steadily and gradually fading for some weeks now, but in the last three nights I have picked up, what looks to be, a rapid drop again. All my mags are in the photometry dB, and also see my attached graphs here.

Best Regards
Ian.

Interesting. I took a spectrum on 10th Nov (Getting rather faint for my standard ALPY so now changed to my lower resolution ALPY200) so it will be interesting to see if there are any changes the spectrum. Here are the spectra for the past couple of months (Observing at high air mass now so the continuum slope may be suspect)

Cheers

SN 2023ixf gets quite some coverage in today’s pre-print “Supernovae in 2023 (review): breakthroughs by late observations” on ArXiv: https://arxiv.org/abs/2311.17732
Focus is on pre-SN properties of this CCSN.
