In this paper results from the optical photometric observations of the pre-main sequence star V1180 Cas are reported. The star is a young variable associated with the dark cloud Lynds 1340, located at a distance of 600 pc from the Sun in the star-forming region in Cassiopeia. V1180 Cas shows large amplitude variability, interpreted as a combination of accretion-induced and extinction-driven effects. Our data from VRI CCD photometric observations of the star were collected from September 2011 to February 2022. During our monitoring, we recorded several brightness dips with large amplitudes of up to 5 mag (I band). At the same time, increases in brightness over periods of several weeks have also been recorded. In this paper, we compare the photometric data obtained for V1180 Cas with observations of other low-mass pre-main sequence objects.
