HR326 H alph annomoly

HR 326 is showing signs of emission within a broad absorption. Can't find it as an e star in the standard tests.

Will process and post tomorrow but if some one could confirm that would be good.

Regards Andrew

Thanks Robin, it shows much more clearly at higher resolution. I attach my spectra at low resolution. It would be easy to miss but after looking at 10's of spectra you get your eye in!

Well spotted Andrew, that emission is very subtle at low resolution. Here is the fully reduced LHIRES 2400 spectrum from last night (heliocentric and tellurics removed) The classic double hump of an edge on disc is clear.

Cheers
Robin
