Top: Proxima Cen photometric light curve (filter RG715) delivered by MEarth DR7 (black dots). The data span a period of 3.2 yr. Negative magnitude simply brighter states of the star. Middle: enlargement of the MEarth DR7 light curve. Original data are plotted as grey dots. The day-averaged photometry is shown with black dots. Bottom: ASAS-SN light curve (black dots) spanning a time period of 2 yr. The mean magnitude of 11.227 mag has been subtracted from the original data for a proper comparison with the MEarth DR7 light curve.
