My spectrum of beta Cephei taken in july showed an emission while spectrum from 2014 didn't (one from Olivier Garde in 2015 seems to show something).
I have taken another spectrum tonight and change seems slow:


Note that spectra have been corrected from heliocentric velocity as well as the radial velocity from CDS catalog, explaining the difference in telluric lines between he two dates...
