Abstract
We report the first results of an observational campaign consisting of coordinated photoelectric photometry of Ex Hya from four observatories at different geographical longitudes for a total of 146 hours in April 1979.
Based on observations obtained at the European Southern Observatory, La Silla, Chile and at the South Affrican Astronomical Observatory, Sutherland, South Africa.
