ASAS-N (blue) and ASAS-S (red) V-band photometry data of AD Leo with respect to the data mean. Only “Grade A” is shown with all 5σ outliers removed. An offset of 25.9 mmag has been accounted for. The uncertainties represent estimated excess variability in the data. The black curve denotes the long-period activity cycle of the star reported by Buccino et al. (2014). The position of the MOST observing run is denoted by a vertical line.
