Using the transition in ${}^{171}$Yb$^+$ as a reference, we determine the transition frequency to be $642\\,116\\,784\\,950\\,887.6(2.4)\\,$Hz. We map out the magnetic field environment using the forbidden $^2S_{1/2} \\rightarrow{}^2D_{5/2}$ electric quadrupole (E2) transition and determine its frequency to be $729\\,476\\,867\\,027\\,206.8(4.4)\\,$Hz.
