It is also suspected of being a flare star. This would be lethal to Earth-type life on planets near the flare star. Gliese 49 has a similar proper motion to the red dwarf flare star V388 Cassiopeiae. While smaller than the Sun, it is relatively large for a flare star. It is classified as a flare star that undergoes intermittent fluctuations in luminosity. It exhibits flare star activity, which is most pronounced at radio wavelengths. This is a flare star that occasionally increases in luminosity. Several star catalogs, including SIMBAD, also classify it as a flare star. In 1951, American astronomer Harlow Shapley announced that Proxima Centauri is a flare star. It was classified as a flare star and given the variable star designation FI Virginis. It is a flare star that undergoes random increases in luminosity. The primary is a flare star that shows periodic increases in activity. Also a flare star, Proxima has minutes-long outbursts where it brightens by over a magnitude. The secondary is a flare star that is referred to as WX Ursae Majoris. EV Lacertae is spectral type M3.5 flare star that emits X-rays.
