Good RI, Christophe
Lines Id. OK, unless [Fe VII]. The yellow giant has low metallicity. Thus no Fe lines (unfortunately!).
But, perhaps, Fe II 5018 during outbursts (at higher resolution)
All the best,
François

Hello François,
Thank you for these explanations !
Spectroscopically,
Christophe

An update.

AG Dra is still in quiescent state (photometry and spectroscopy)
Last results from spectra (Echelle) gathered in ARAS base:
Interesting: the light curve is steady at Mag V ~ 9.7. The EW of the main lines is increasing slowly.
Good coverage, Excellent results, thanks to all.
We are undergoing the observations at a low cadency (low and higher resolution).
Even if, this year, the target doesn't produce an outburst event, the data will be very important to produce a baseline (Joroslav's communication).

All the best,
François

Joroslav's comments:
The behavior of AG Dra is quite interesting. The brightness doesn't seem to change significantly. Absorption in the blue wing of H alpha is still quite prominent. However, EWs are slowly increasing (not only for low excitation lines, for which the changes with the orbital period are expected). As I said previously, we will see how the evolution will continue. Everything is possible, this is a very unusual activity stage.

Ma contribution sur cette étoile, spectre prit hier soir :

Hello all,

Here is my last contribution to the AG Dra monitoring.
I obtained the following spectrum the 4th of May at 22 h 31 TU with my Alpy 600 (resolution of 506, JJ = 2458608.4388) and an acquisition time of 35 min :
Clear skies,

Christophe BOUSSIN

Still quiescent Only the singlet He I 6678 is sllghtly increasing: Ongoing observations until late May, the outburst remains possible.
