[] V455 And: high-speed photometry on 100117



We performed high-speed photometry of the dwarf nova, V455 And on 17 Jan 2010 with a time-resolution of 2 s. V455 And experienced a WZ Sge-type superoutburst in 2007. This object is also known as an intermediate polar, whose spin period of the white dwarf is 67 s. The figures show our preliminary results: the light curve (the upper panel) and power spectrum (the lower panel) in 17 Jan. The features of the light curve and power spectrum are almost same as those observed on 23 Sep 2009. The object is still slightly brighter than the quiescent state observed before the 2007 superoutburst. We will continue the observation of this object to find a possible change in the structure of the power spectrum.
