Yes it is real. I also see it in a Star Analyser spectrum I took a couple of days ago. It is a blend of several lines ~4500-4600A unresolved at the Star Analyser resolution Here it is overlaid on a spectrum from David Boyd in the BAA database (red)
(It looks quite intense relative to H gamma because H lines are narrow compared with the Star Analyser resolution so are reduced in height)
Cheers
