This paper presents the findings of an analysis of the light curve of the star IRAS07080+0605, a member of the FS CMa class. The analysis was conducted using data from the ASAS-SN survey, collected between 2014 and 2025. The year-by-year analysis of the ASAS-SN time series in the g filter reveals that the systems period changes over time, and the shape of the phase curve varies during individual intervals. The asymmetry observed in the phase curves suggests potential orbital changes, possibly related to the systems dynamics, including variations in the separation between the components. Additionally, we describe changes in the luminosity amplitude of IRAS07080+0605, which may reflect alterations in the stars physical state, such as pulsations in its outer layers or interactions with its environment.
