After writing about the possibility that Red and Brown Dwarf star systems offer a possible environment conducive to life; Wal Thornhill wrote this caveat about brown dwarf stars. The statement applies to Red Dwarfs too (both types are in the lower right of the H-R diagram) and both have a tendency to flare.
However, the brown dwarf ‘Garden of Eden’ comes with a caveat. Stars off the main sequence do not have the self-regulating photospheric discharge to smooth out variations in electrical power input. Consequently, brown dwarfs are subject to sudden outbursts, or ‘flaring,’ when they encounter a surge in the circuit that powers them. These flares could cause sparking to and between the satellites orbiting inside the sheath and lead to sudden extinction events, vast fallout deposits and fossilization. There is much food for new thoughts!

Proxima b is a planet which is believed to be orbiting Proxima Centauri in the "Goldilocks" zone.
How has this and previous flares from Proxima Centauri affected the possibility of life on Proxima b?

The closest star to our solar system is the red dwarf Proxima Centauri. Recently it emitted a giant flare which was 100X more powerful than a typical flare from the Sun.
