yes a very good target but the weather at home is really not good....

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

Mike Harlow has posted an objective prism spectrum on his BAA page

Hello Robin
nice target. Waiting for better weather condition.

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

gives a good SNID match to SN 1998S (type IIn)

downloadable from the BAA database

https://britastro.org/specdb/data_graph ... s_id=13774

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)

This one is in both absolute and relative flux

Now a year old so here is a spectrum in the nebula phase at V mag ~18 (tough in moonlight and the twilight skies here at this time of year)

Here is the animation from September 2023 - February 2024 showing it moving into the nebular phase
