RZ Leo superhump period update Dear Colleagues, We have received excellent data from Brian Martin and Jochen Pietz. (Thanks to Brian, the gap between Brian's and Kyoto observations was only 30 min!). The analysis of all data since Dec. 23.5 UT up to the Kyoto Dec. 29 full run (a total of 4598 points) has yielded the best superhump period of 0.07863 d. Please note this value is rather preliminary, since strong beat modulation and period change may have affected the period determination. Intensive detailed analysis is undertaken by Ishioka-san, and will be announced duly. Regards, VSNET Collaboration team
