CU Vel: further observations from Peter Nelson Dear Colleagues, We have received further very high-quality observations on Dec. 16 from Peter Nelson. The light curve now clearly shows a transition from the early stage superhumps. A preliminary timing analysis semes to have further strengthened the unusual period change (slightly positive Pdot). CU Vel must be an ususual SU UMa-type dwarf nova in its superhump period change. A full analysis with the updated data is in progress. Further observations are still very encouraged!
