Congratulations to everybody for your nice spectra.

Hi Fran

This is this correct range and resolution.

All the best for the next months until the expected outburst

Hi all, new observation for April 17.
Steve suggests : near IR for monitoring O I 7772-7774, 8446 - LISA IR should be a must.
Tried with Lhires III and 600 l/mm grating. Wratten 25 filter to avoid 2nd order contamination.

Image

Neutral oxygen line at 7772 A is not visible while at 8446 A is weak. Is it a quiescent state spectrum?

AG Dra le 19/04/17 en basse résolution, calibré en flux absolu avec la fente photométrique Alpy, étoile de référence SAO 64686

EDIT: attachement supprimé, erreur sur la calibration en flux absolu

Bon ciel !

Bonjour Jean-Pierre,

Le spectre est bon,
Mais pas la calibration en flux
Il faut attendre plutôt 1E-12 comme ordre de grandeur

Good!
Tu peux m'envoyer le fit pour la base. Il y sera le bienvenu.
Un spectre par semaine serait un bon rythme pour détecter l'outburst attendu.
Bonne continuation,

François
