Prominence maps of V530 Per reconstructed from the data of 29 Nov., 2006 (top) and 05 Dec., 2006 (bottom). The inner, filled blue circle represents the stellar surface. Radial ticks inside this circle give the rotational phases of our observations. The outer dashed circle is the corotation radius. The color scale depicts the local Hα equivalent width, in units of picometers per 8 km s⁻¹ square pixel.
