Sažetak
Light variability of BD +61 2213, first suspected more than 20 years ago, is confirmed on the basis of observations from three observatories. The light of BD +61 2213 apparently varies with the period of 1.2028251 days and a double-wave light curve. Five available radial velocities of the star also define a large-amplitude curve with the same period. The star is, therefore, a binary as suspected earlier. We conclude, however, that it is more probably an ellipsoidal variable than an eclipsing binary. Its further spectral and photometric monitoring is desirable, especially since an accurate determination of its physical elements could also improve the knowledge of the distance of th NGC 7160 cluster.
