Autor: Oizumi, Shota, Omodaka, Toshihiro, Yamamoto, Hiroyuki, Tanada, Shunsuke, Yasuda, Tatsuki, Arao, Yoshihiro, Kodama, Kie, Suzuki, Miho, Matsuo, Takeshi, Maehara, Hiroyuki, Nakajima, Kazuhiro, Dubovsky, Pavol A., Kato, Taichi, Imada, Akira, Kubota, Kaori, Sugiyasu, Kei, Morikawa, Koichi, Torii, Ken'ichi, Uemura, Makoto, Ishioka, Ryoko, Tanabe, Kenji, Nogami, Daisaku
We report on time-resolved CCD photometry of four outbursts of a short-period SU UMa-type dwarf nova, V844 Herculis. We successfully determined the mean superhump periods to be 0.05584(64) days, and 0.055883(3) for the 2002 May superoutburst, and the

Autor: Ishioka, Ryoko, Kato, Taichi, Uemura, Makoto, Billings, Gary W., Morikawa, Koichi, Torii, Ken'ichi, Tanabe, Kenji, Oksanen, Arto, Hyvonen, Harri, Itoh, Hitoshi
We report the first time-series observations of the short outburst of the proposed intermediate polar HT Cam (=RX J0757.0+6306). On 2001 December 29, we detected the object was undergoing a bright outburst at the magnitude of $m_{vis}=12.2$. Followin

1998 Superoutburst of the Large-Amplitude SU UMa-Type Dwarf Nova WX Ceti
Autor: Kato, Taichi, Matsumoto, Katsura, Nogami, Daisaku, Morikawa, Koichi, Kiyota, Seiichiro
We observed the 1998 November superoutburst of WX Cet, a dwarf nova originally proposed as a WZ Sge-like system. The observation established that WX Cet is an SU UMa-type dwarf nova with a mean superhump period of 0.05949(1) d, which is 2.1% longer t
