Hi
I made a spectrum of 69 Ori saturday 24th Jan 2015 - and I was surprise to see an emission profile. All spectra in beSS shown an absorption one. I double checked my field but you never know...
So if someone can confirm, that would be great !
Thanks
Valerie

Re: Be Star 69 ori
Very nice spectrum... and thank you for the confirmation. I did not observe from paris for a while, so I was a little bit "rusty".
The first observation was in feb 2008 and there are 18 spectra since then in BeSS... all in absorption.
Thanks Tim

Re: Be Star 69 ori
The feature around 6300A in Tim's spectrum is interesting. It looks like a partially resolved molecular band which I did not expect for a hot star. Does anyone know what it is ?
EDIT: It is an O 2 Telluric band of course ! Silly me
