Hanindyo Kuncarayakti, Mamoru Doi, Hakim L. Malasan +20
We introduce the Dichroic-Mirror Camera (DMC), an instrument developed at the University of Tokyo which is capable of performing simultaneous imaging in fifteen bands. The main fea…
Outburst of a WZ Sge-type dwarf nova, AL Com in 2007
M. Uemura, A. Arai, M. Sasada +8
We report photometric observations of AL Com during its rare outburst in 2007. The light curve is reminiscent of its past superoutbursts in 1995 and 2001, except for the rebrighten…
The 2003 Superoutburst of an SU UMa-type Dwarf Nova, GO Comae Berenices
Akira Imada, Taichi Kato, Makoto Uemura +19
We photometrically observed the 2003 June superoutburst of GO Gom. The mean superhump period was 0.063059(13) d. The resultant data revealed that (1) the obtained light curve conta…
Discovery and Photometric Observation of the Optical Counterpart in a Possible Galactic Halo X-ray Transient, XTE J1118+480
M. Uemura, T. Kato, K. Matsumoto +7
We discovered the optical counterpart about 13 mag of a soft X-ray transient, XTE J1118+480 on 2000 March 30. We perform astrometry and provide the accurate position as R.A. = 11h1…
