IX Dra superoutburst Dear Colleagues, The Kyoto team (observers: M. Uemura and R. Ishioka) has recorded an ongoing superoutburst of IX Dra (the analysis has been delayed, as in Var73 Dra). The object was caught in rise on October 10. A superoutburst plateau has lasted since then. Superhumps have been detected on all analyzed runs during the superoutburst pleteau. The detection of likely superhumps during the rising branch makes a further confirmation of early-time appearance of large-amplitude superhumps in ER UMa stars (Kato et al. (1996) PASJ 48, L5). IX Dra is one of rare ER UMa-type dwarf novae (Ishioka et al. (2001) PASJ 53, L51). Since the object will be still bright for several days to a week, further detailed observations will be welcomed. When reporting the data, please also send them to Uemura-san and Ishioka-san (uemura@kusastro.kyoto-u.ac.jp and ishioka@kusastro.kyoto-u.ac.jp). Regards, Taichi Kato VSNET Collaboration team
