BD+64 106 in emission New Be ?

Yesturday i observe the star BD+64 106 CDS coordinate: RA 00h57m36.6989 DEC +64d51m34.946s
This star according CDS is a normal B1V star, but i observe a strong emmision in Ha. So perhaps a new Be star.

The continium look very strange for a B1V star... Perhaps some thing wrong with instrumental response. I observe
just after the target, the reference star HD13267 and calculate my instrumentale response with.

The resolution is about 600.

Thierry,
Il peut arriver que l'extinction interstellaire soit trés élévée
Pour E(B-V) = 0.7 , le continuum d'une étoile de type B devient presque horizontal
Deux exemples sur http://www.astronomie-amateur.fr/feuilles/Spectroscopie/Be.html
En tout cas ce serait super si tu avais découvert une Be
Andrew est un bon stimulant !
Amicalement
François

Congratulations Thierry, I hope you get confirmation soon and it turns out to be a new Be star.
