Authors: Qingfeng Pi, Liyun Zhang, Zhongmu Li, Hongyan Sang, Zhongzhong Zhu

We present our new photometry of DV Psc obtained in 2010 and 2011, and new spectroscopic observation on Feb. 14, 2012. During our observations, three flare-like events might be detected firstly in one period on DV Psc. The flare rate of DV Psc is about 0.017 flares per hour. Using Wilson-Devinney program, we derived the preliminary starspot parameters. Moreover, the magnetic cycle is 9.26(±0.78) year analysed by variabilities of Max.I - Max.II.
