Well, I've been discussing on this one with John Greaves and he suggests
this is a BY Draconis type.
I think he's right, since it looks *too* periodic for a semiregular star and
its period is too short.
The question is: is there any information bout its luminosity class?
If it's a BY type, this might be an M-dwarf.
Thanks, John.

Sebatsian.
