Angular diameter is approx. 65" after allmost 72 hours since my 1. image on 2023-12-01 16:38UT ( 25"). Which gives an updated expansion of (65" - 25") / 72 hours = 0.56" / hour
Estimared start of outburst, 25" / (0.56" / hour) = 45 hours before my 1. image : Approx. 19.00UT 29. November 2023

This comet comes closer to the sun with more and more varying shapes, an interesting process on its way towards disintegration into an orbital meteor cloud in the distant future.

It also behaves like 17P/Holmes on November 11th, 2007 and 29P/Schwassmann-Wachmann . Also see 29P at the bottom.
