Great observations ! Congratulations!

This is indeed a very interesting target. Nicely visible at the beginning of the night.

Friends from TJMS (@vienney_j_m 77 Buthiers France) were able to get spectra from at2024abqt .  
This is clearly a nova with a strong Ha emission line. I expect they will publish their results quickly here.

Which is not surprising: the nova has faded already…
