Twenty-eight angular diameters for late-type stars by the lunar occultation technique
New angular diameter measurements obtained with an infrared photometerare reported. The stars observed include three Mira variables and ninecool IRC objects. Repeat measurements are reported for five stars. Theobservations include numerous daytime and reappearance events.
