  We report optical time-resolved photometry of the CRTS transient
CSS091109:035759+102943. Pronounced orbital variability with a 114 min period,
large X-ray variability and the IR to X-ray spectral energy distribution
suggest a classification as a magnetic cataclysmic binary, a likely AM Herculis
star or polar.
