BO Microscopii

This relatively young sunlike star rotates very fast, which gave it the nickname 'Speedy Mic'. On it for the first time the source of a flare was localized. The location of the flare, which was 100 times stronger than a large solar flare, surprisingly does not correspond to the star's spots.

Constellation: Microscopium
Distance: 150 light-years
Spectral class: K0V
Visual magnitude: 9.44
