Hi Patrick, 

 

I uploaded…

Hi Patrick, 

 

I uploaded my two (original plus another from last night) spectra to avspec, but neglected to name them with N Mus 2022 and only included the asassn-22hw identifier. Please let me know if I should delete and upload with N Mus 2022 and/or Asassn-22hw in the object name field of the fits file.

 

Cheers,

V415 Muscae = Nova Muscae 2022 = ASASSN-22hw

Hi Hamish,
 
Sorry, I saw your posting only now (unfortunately I do not get notification mails from AAVSO for this forum section).
There is now a GCVS name for this nova: V415 Mus(cae)
Maybe you can upload your spectra under this name.
 
Cheers,
Patrick
