From his observations Hoffmeister deduced that NSV 02980 was an RR Lyr or W UMa type star with a photographic magnitude variation range from 12.0 to 12.5. No photometric elements or even spectral class have been given. The observations collected during this observational period show that NSV 02980 is in fact an overcontact binary star.

2 Figure 2 Figure 2 shows the obtained light curve. Light curve dispersion does not allow us to accurately determine the actual shape and depth of primary and secondary minima, but it seems that the primary minimum is a transit with a 0.45 magnitude depth and the secondary minimum is an occultation with a 0.43 magnitude depth.
