apparently its Halpha is rarely static, so might be of interest as a longer terms target for some.

 

Note that RS CVn do not also have to have eclipses, so photometrically this object is likely quite low amplitude around visual, but variant in Halpha strength and profile.  The activity will be chromospheric and occasional flaring in said.
