M-dwarfs are small, cool and generally have a high activity. They are also most likely to be hosts of rocky exoplanets. Since these planets are often located in the habitable zone, which is relatively close to the star, flares are able to severely impact an exoplanet's atmostphere. Knowing how often flares occur is crucial to evaluate a planet's habitability. We analyzed the occurrence rate of flares on Proxima Centauri, our closest neighbour and a M-type star, using the observational data produced by mascara. In the period of 16 November 2017 until 31 December 2018, we detected 2 flares. The peak flux of the first flare was 4.3 times as much as the star's quiescent flux, and 4.0 times as much for the second flare. Based on the number of observation hours, approximately 14 flares a year are expected to occur on Proxima Centauri.
