The Superoutburst of SDSS J162520+120308 in July of 2010

摘要

We report photometric observations a new dwarf nova during outburst occurred in July 2010. The outburst amplitude was about 6 magnitudes and it lasted 8 days. Superhumps were detected in the light curve of this nova and the mean superhump period was measured to be Psh=0d.096042(7). During the decline the superhump period changed from 0d.0927 to 0d.1150. Our observations are consisted with SDSS J162520+120308 being a new SU UMa dwarf nova in the gap on the period distribution of cataclysmic variables.
