Bonjour,
merci François pour l'info sur la raie 6614A car je la détecte aussi sur certains spectres (dont psi Per et V442 And) et je me demandais ce que c'était! Je le mesure plutôt à 6613.4A.
Cordialement,
Olivier

V442 And Be star in outburst - update
Hello all, a quick update on V442 Andromedae which went into outburst end of august. The outburst seems done now (to be confirmed) but one spectrum per week would confirm it. Here is the spectrum from last night with no emission visible: V442And.png Once the outburst end if confirmed, it would be gr...

Hello all, as you know, B[e] have been added in BeSS database recently. Couple of us recently took spectra of V594 Cas, a magnitude 10.6 B8I[e], and results seem to be very interesting. Helpha was showing a P Cygni profile with absorption near -300km/s on nov 16th but absorption disapeared the follo...

Re: 28 Tau ARAS monitoring
Ernst,
thanks - this is what I assumed but prefered to ask. I know how hard it is to reconcile data received directly and the data only uploaded in BeSS - I am doing it on V442 And for exemple. So I just feel the tremendous work you are doing there - and not only on 28 Tau!
Cordialement,

Re: 28 Tau ARAS monitoring
Ernst, I have several 28 Tau spectra in BeSS database. I know it is only six but three of them in august-september this year. I do not see my name on your graph so I am guessing you aren't using any of them. Are you taking spectra from BeSS or only using spectra that are sent to you directly? Cordia...

Re: V442 And Be star in outburst
Hello,
V442 And is still showing emission in Halpha. While the V+R seems now more stable, the distance (speed) between the two peaks seems to increase.
