Hello all,

Thank you very much François for this field, because the Nova is not so easy to find !
Here is my contribution to the monitoring of Nova Ser 2025.
I obtained the following spectrum the 20th of July at 23 h 24 UT with my Alpy 600 (resolution of 516, JJ = 2460877.4753) and an acquisition time of 40 min (4 x 600 s) :
Nova Ser 2025 on July 20th, 2025 (3776-7560 A)
Nova Ser 2025 on July 20th, 2025 (3776-7560 A)

Clear skies,

Christophe BOUSSIN

These three spectra of Nova Ser 2025 were collected at ~24 hr intervals, the first by Christophe Boussin and the other two by me, all with the Alpy 600. The three spectra have been added to the ARAS Spectral Database: https://aras-database.github.io/databas ... r2025.html

Hello,

After a lot of cloudy days I could observe Nova Ser 2025 yesterday night. It was on the boundary of SMM remote equipment,
but I have been able to reach this graphics by a NOU_T echelle.

Cheers, J. Guarro.
