Angular diameters of 0″.0056 ± 0.0011 and 0″.0049 ± 0.0008 have been calculated for the red giants 46 Leo and φ Aqr respectively from occultation observations. The occultation curves of α Lib and ε Cap show that they are binary systems. The separation of the components of the visual binary ε Ari, as calculated from its occultation curve, is 1.3 times its reported value. The occultation curve of α Leo shows distortion effects which are attributed to irregularities in the lunar limb.
