1 GCVS Team Wachmann [A.A.Wachmann, Bergd Abh 7, N4, 1964.] assigns the variable to the RRab type with the elements Max = 2433001.371 + 0.8743887*E, but notes a considerable dispersion of the points around the mean light curve obtained with this period. As the periods by Hessner (PH) and Wachmann (PW) are mutually related (1/PW ~1/PH + 1) it is more probable on account of the above mentioned circumstance that the variable belongs to cepheids.
