The projected rotational velocity at the equator of this star is about 135 km/s (84 mi/s), which, with an estimated inclination of 70° to the line of sight from the Earth, means it completes a rotation every 0.380 ± 0.004 days (9.120 ± 0.096 hours).

As many as 25 prominences have been observed simultaneously, extending outward as far as 3.6 times the radius of the star.

BO Mic is a flare star that undergoes sudden increases in X-ray and ultraviolet emissions.

These events can emit a hundred times more energy than large solar flares.

[7] Speedy Mic is one of the most active stars in the vicinity of the Sun.
