An R~5500 LHIRES spectrum of Halpha/He I 6678 last night. 

Lots of evolution over a day in spectra in BAA database

The interstellar line at 6613 is strong too. (I did a bit of Googling on that last night and it seems although it is thought to be molecular in origin, the species does not seem to be known. Does anyone know more about this )
