Approximately -2.6 to 5.7, "apparent magnitude".
Mercury's brightness varies as it orbits the Sun.
Mercury is difficult to see because it's so close to the Sun in the sky.
So, its apparent magnitude is a bit misleading as a guide to ease of observation.
(Also, remember that it is dangerous to look directly at the Sun.
Astronomers have developed safe methods for observing things close to the Sun.)
