Re: TCP J04291884+4354232 possible nova mag 10.2
Hi all, great spectra!
My contribution using Lires III and 600 l/mm grating.
H-beta and Fe II region
H-alpha, Fe II and neutral helium
Neutral oxygen and helium, maybe C II
(W25 filter to avoid 2nd order contamination)

Comme Olivier avec l'Alpy j'ai un spectre un peu bossu qui monte du bleu vers 5800A puis après qui descend.
Olivier, tu montres des évolutions de la raie Ha extrêmement rapides, ça évolue aussi vite ?

Impressive change in one day. See also Olivier Garde's graphs.
The red component (linked to the absortion - 850 km/s) disappear EBE = Etienne Bertrand

Bonne continuation!

Second night on this Nova with a bad weather (feezing fog).
Here's the evolution of the balmer lines in one day

A spectrum taken a few hours later (LHIRES1200 R~5600) confirms the continuing evolution (The hump on the red edge of H alpha is no longer clear)Olivier GARDE wrote:

Hello,
My little contribution ...

Steve Shore recalls that the near IR is very also important.
"somehow it's really essential that some spectra cover 7000-9000A (O I, Ca II, Paschen)"
Lhires III 600 l/mm
UVEX, LISA IR
Of course visual range remains very useful too!
Do not hesitate to share your observing session (in real time) in order to optimize the acquisitions between the observers.

Ce soir le spectre a encore changé !! Incroyable cette évolution aussi rapide !
(je suis sur la cible avec l'Alpy, je vous partage le 1er spectre)

Trés bon, Etienne,
Oui, les absorptions augmentent, on doit être proche du maximum.
Un bonheur cette nova dans l'hémisphère nord (surtout par le stemps qui courrent ...)
