Figure 2: The general photometric behavior of SS UMi during the whole 2004 campaign. Visual estimates collected by AAVSO observers are shown as open circles and the CCD observations described in this paper as black dots. The open triangles correspond to the "fainter than'' estimates from AAVSO. Big filled triangles point to the expected positions of superoutbursts assuming 84.7 days supercycle length. Two arrows show the moments of maximum magnitude of the recorded superoutbursts. |
