  HD144941 is an evolved early-type metal-poor low-mass star with a
hydrogen-poor surface. It is frequently associated with other intermediate
helium-rich subdwarfs and extreme helium stars. Previous photometric studies
have failed to detect any variability. New observations with the K2 mission
show complex but periodic variations with a full amplitude of 4 parts per
thousand. It is proposed that these are due to an inhomogeneous surface
brightness distribution (spots) superimposed on a rotation period of 13.9+/-0.2
d. The cause of the surface inhomogeneity is not identified, although an
oblique dipolar magnetic field origin is plausible.
