RX Vol superhumps Dear Colleagues, We have received new observation from Berto Monard. The data indicate that the superhump amplitude is rather rapidly decreasing. Only a few instances are known with this degree of rapid amplitude decrease during such an early stage of a superoutburst. This may be an indication of a coming drastic change in the superhump properties, as we saw in V1028 Cyg superhump regrowth and brightening. The superhump period seems to have experiencing a stepwise change at around 1.3 d after the initial observation (a stepwise decrease by a small amount). This needs to be confirmed by further continuous observations. The RX Vol observing campaign has been very successful, too. Please continue observing this top-priority target! Regards, Taichi Kato VSNET Collaboration team
