Аннотация:New CCD photometric observations of DV UMa were carried out by using three different telescopes. Beginning on 2009 November 12, this star was continuously monitored with the 2.4m telescope at the Lijiang observational station of Yunnan Observatories (YNAO). To collect more data for this binary, an observation was made on 2016 March 29 with an Andor DW436 1K CCD camera mounted on the 85cm reflecting telescope at the XingLong station of the National Astronomical Observatory and another observation made on 2017 January 23 with an Andor DW936 2K CCD camera attached to the 1.0m reflecting telescope at YNAO. During the observations, no filters were used in order to improve the time resolution.
