Volume 34 number 2 (2006)
Analysis of CCD data collected in V- and R-band over the last 3 months of 2005 has lead to a revised ephemeris and orbital period for SW Lac. A Roche-type model invoking a dark starspot on the cooler, more massive component has provided a theoretical fit of light curve data that largely accounts for the observed peak asymmetry and unequal successive maxima.
