RZ Leo: superhump period decreased Dear Colleagues, The Kyoto team succeeded in obtaining a continuous 6.5-hour run on Dec. 24. We have also received a 3.5-hour data from Kiyota-san (Tsukuba, Japan). A very preliminary analysis has shown the decrease of the superhump period to 0.079 d. The combined set of data spanning Dec. 23-24 has yielded 0.0787 d. The amplitude of the superhumps now exceeds 0.4 mag. More detailed analysis using all data, submitted to the VSNET Collaboration team, is in progress. Regards, VSNET Collaboration team
