A new relative orbit solution with new dynamical masses is determined for the nearby white dwarf - red dwarf pair 40 Eri BC . The period is 230.09 \pm 0.68y . It is predicted to close slowly over the next half-century getting as close as 1 \farcs 32 in early 2066 . We determine masses of 0.575 \pm 0.018 { \cal { M } } _ { \odot } for the white dwarf and 0.2041 \pm 0.0064 { \cal { M } } _ { \odot } for the red dwarf companion . The inconsistency of the masses determined by gravitational redshift and dynamical techniques , due to a premature orbit calculation , no longer exists .
