We report extensive photometry of the dwarf nova KS UMa throughout its 2003 superoutburst till quiescence. During the superoutburst the star displayed clear superhumps with a mean period of Psh = 0.070092(23) days. In the middle stage of superoutburst the period was increasing with a rate of $\dot P/P = (21\pm12)\times 10^{-5}$ and later was decreasing with a rate of $\dot P/P = -(21\pm8)\times 10^{-5}$. At the end of superoutburst and during first dozen days of quiescence the star was showing… 
The CUrious Variables Experiment (CURVE). Variable properties of the dwarf nova SS Ursae Minoris
We report on extensive photometry of the dwarf nova SS Ursae Minoris throughout nine months of 2004. In total, we recorded two superoutbursts and 11 normal outbursts of the star. SS UMi has been
The dwarf nova MN Dra: Periodic processes at various phases of the supercycle
We analyze photometry of the dwarf nova MN Dra carried out using various instruments at four observatories on 18 nights between May 20 and June 28, 2009. The observations cover a variety of activity
Survey of Period Variations of Superhumps in SU UMa-Type Dwarf Novae
We systematically surveyed period variations of superhumps in SU UMa-type dwarf novae based on newly obtained data and past publications. In many systems, the evolution of superhump period are found
CURious Variables Experiment (CURVE): CCD photometry of active dwarf nova DI Ursae Majoris
Context. We report an analysis of photometric behaviour of DI UMa, an extremely active dwarf nova. The observational campaign (completed in 2007) covers five superoutbursts and four normal outbursts.
Photometric Observations of an SU UMa-type Dwarf Nova, VW Coronae Borealis, during Outbursts (Special Issue: Resent Results from VSNET)
We report on photometric observations of an SU UMa-type dwarf nova, VW CrB, during two superoutbursts in 2001 and 2003 and a normal outburst in 2003. Superhumps with a period of 0.07287(1)d were
Photometric Studies of a WZ Sge-Type Dwarf Nova Candidate, ASAS 160048$-$4846.2
We report on our time-resolved CCD photometry during the 2005 June superoutburst of a WZ Sgetype dwarf nova candidate, ASAS 160048-4846.2. The ordinary superhumps underwent a complex evolution during
The 2003 superoutburst of a new su uma-type dwarf nova,Go comae berenices
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 contained a precursor,
Superhumps in a Rarely Outbursting SU UMa-Type Dwarf Nova, HO Delphini
We observed the 1994, 1996, and 2001 outbursts of HO Del. From the detection of secure superhumps, HO Del is confirmed to be an SU UMa-type dwarf nova with a superhump period of 0.06453(6)d. Based on
Multicolor Photometry of an Outburst of a New WZ Sge-Type Dwarf Nova, OT J012059.6+325545
We present our photometric studies of a newly discovered optical transient, OT J012059.6+325545, which underwent a large outburst during the period between 2010 November and 2011 January. The
