We present the first high-resolution spectra of the W UMa contact binary V524Mon. The spectra of the two components are very similar, resembling a G5 and aK0. We find the radial velocities and rotational velocities consistent withcorotation. We estimate the radii and the masses and derive a mass ratioM_2/M_1 = 2.1. We confirm that V524 Mon is a W-type contact system, likelyenclosed in a common convective envelope, as found by Samec & Loflin (2003). Wedo not find evidence for the expected level of emission in the chromosphericCaII H and K lines, neither H_alpha, indicating that the magnetic activity ismuch weaker than expected or that other processes are hampering chromosphericemission.Comment: 5 pages, 3 figures.
