The apparent disks of Capella A and B have been resolved with a two-telescope interferometer operating at 12- to 20-meter baselines. The angular diameters are, respectively, 5.2 plus or minus 1.0 and 4.0 plus or minus 2.0 milliarcsec. Through continued observation, further improvements are possible in the accuracy of diameter and orbital determinations.
