Hi all, recently I'm dedicated to the monitoring of faint Be stars with a low power resolving spectrograph, with the aim to verify any large changes.
I would like to report a possible h-alpha line evolution (decrease) for IP Per. Here you find a comparison with a previous BeSS spectrum.
Can anyone confirm it with a better resolution spectrum?
Thank you.

Re: Be star IP Per h-alpha evolution
Hello Umberto,
I checked this star last night (LHIRES 1200 R~5500) The emission now looks similar to that recorded in 2012. Sorry I did not check it earlier
Cheers
Robin
