Measuring the diameter of Juno
The determination of the diameter of the asteroid Juno upon itsoccultation of the star SAO 115946 in December, 1979 is discussed. Thetimes of immersion and emersion of the star behind the minor planet weremeasured by a set of six portable telescopes, including four two-channelphotoelectric photometer systems based on a 14-inch telescope,distributed from north of the expected northern limit of the occultationpath to the southern limit through southern California. Observationswere obtained from the four southern field stations, and indicate thedisk of Juno to be elliptical, with major and minor axes of 293 and 252km, respectively. A simultaneous search for any possible satellites ofJuno did not yield any positive results. It is concluded that the methodemployed represents an effective means for the accurate determination ofasteroid sizes and shapes.
