The authors parameterize the photometric distortion waves in the short-period RS CVn system BH Vir by a dark, circular spot model for the active regions on the primary stars. From recent observations and archival source, they infer the positions and areas of the active regions and also evaluate the temperatures of the spotted regions relative to the photospheres. For BH Vir in 1986, Tspot = 4900K ± 500K. The active regions tend to occur at high latitudes (near 45°) and at preferred longitudes (active longitude belts) near 90° and 270°.
