Abstract

The eclipsing variable YY Eridani was discovered by C. Hoffmeister on Sonneberg plates. At Abastumani Observatory YY Eridani was being observed photographically at the Newtonian focus of the 13-inch reflector from February 2 to March 18, 1937 and, moreover, in December of the same year. In all 181 images fit for measurements were obtained. The photographs were taken on Ilford Monarch plates (emulsion 8474 A) with 2 minute exposures. The measurements obtained enabled us to determine the following correction of the period: ΔP=-0d.000002; The new elements are: Min=2427364.440+0d.321494.E The photographs were taken with the assistance of K.G. Zakharin, E. Dolidze took part in calculations. August, 1938
