RW Cep is experiencing an unusually deep dimming currently (similar to the Great Dimming in Betelgeuse ?) https://www.astronomerstelegram.org/?read=15800 Currently mag 7.5 it is bright enough for high resolutions but it is not clear what wavelengths would be specifically interesting so Echelle spect...

There are some interesting fast changes in EM Cep currently (disc loss?)

Some professionals do make the effort though. For example I was contacted by the lead author of this paper for permission to use my classifying spectrum of SN 2018gwo on TNS and I was made a co-author and invited to comment on the paper before publication https://ui.adsabs.harvard.edu/abs/2020ApJ......

This supernova features in a recent publication. There is a S&T article about it here https://skyandtelescope.org/astronomy-news/supernova-cosmic-speed-bump The original paper is here https://iopscience.iop.org/article/10.3847/2041-8213/ac7235 and includes the two 2SPOT spectra submitted to TNS ...

This paper which attempts to model the line profiles shows similar shaped [OIII] and H alpha lines, with some additional higher velocity components The precessing jets of classical nova YZ Reticuli Dominic McLoughlin, Katherine M Blundell, Steven Lee, Chris McCowage Monthly Notices of the Royal Astr...

Thanks Francois, The fits files are read correctly by ISIS and according to the paper they have not been corrected for IS reddening so that is good news. (I had to right click to download them and accept that they might be dangerous using Chrome !) I wonder if the Indo-US Stelib spectra on the same ...

A possible supernova AT2022zjo has been reported by an amateur team in NGC2152 06:00:55.210 -50:44:27.50
https://www.wis-tns.org/object/2022zjo
At mag 16.5 (5 days ago) and close to the galaxy core, it is a tough target but possible for a 2SPOT classification perhaps ?
