It is now mag 12 and still rising. No amateur spectra yet? I am surprised. (Only clouds for me since discovery)

A low resolution (ALPY600) spectrum last night (poor conditions, high cloud, twilight

It could be bright enough now for high resolution spectroscopy from a good observing site

An animation showing the evolution over the past week. (The temperature is dropping and the flash ionisation phase He lines have gone)

Catching up with some more animations (I am still following it but at lower resolution with the ALPY200 now it is ~mag 16.5)
