RZ Leo rebrightening update Dear Colleagues, The Kyoto team and S. Kiyota (Tsukuba, Japan) ontained a nearly continuous light curve of the rebrightened RZ Leo. The object had returned to its pre-fading magnitude, as on Jan. 4. There was very little fading throughout the run. Although low-amplitude variations were present, superhumps were less prominent (less than 0.1 mag) than on Jan. 4. Further analysis will be undertaken by Ishioka-san et al. More observations are encouraged, as described in vsnet-campaign 673. Observations in the coming nights will be most discriminating to the nature of the rebrightening. Regards, VSNET Collaboration team
