The first direct observation of a hyperfine splitting in the optical regime is reported. The wavelength of the [ital M]1 transition between the [ital E]=4 and [ital F]=5 hyperfine levels of the ground state of hydrogenlike [sup 209]Bi[sup 82+] was measured to be [lambda][sub 0]=243.87(4) nm by detection of laser induced fluorescence at the heavy-ion storage ring ESR at GSL. In addition, the lifetime of the laser excited [ital F]=5 sublevel was determined to be [tau][sub 0]=0.351(16) ms. The method can be applied to a number of other nuclei, and should allow a novel test of ED corrections in the previously unexplored combination of strong magnetic and electric fields in highly charged ions.
