| Sumario: | This WUMa star, classified as FOV, has been observed photoelectrically with the 40 cm telescope, N°2, at Cerro Tololo. The observations in R, I were made simultaneously with U,B,V observations by Santiapo Tapia with the 40 cm Cerro Tololo telesco pe N°1. Our observations confirm the period given bv A.W.J. Cousins. An analysis of the variation of V-R suggests the existence of a red excess before minima and a blue excess after them. |
