Robin Leadbeater had highlighted the call by Paul Roche (Cardiff University) to observe this star photometrically and spectroscopically - see

I now have four observations of H alpha for this target  (one attached here). I *think* I can see some cyclic activity too... There is a gif at

which was constructed using the animation tool in ISIS, and which shows this I think.

(The gif website is pretty distracting - just right click, save and view locally. Unfortunately we can't upload gifs here...))
