A new RR Lyre star in Leo, discovered by Huruhuta (1983), was observed in 1984 February, March and May using a UBV photometer attached to the 91-cm Reflector of McDonald Observatory. Results of about 420 observations show that the period is 0.67385 +/- 0.00001 d, instead of the 0402132 d, given by Huruhuta. The derived epoch formula magnitude and colours at maximum are. Max = JDH 2445741.159 (+/-0.002) + 0.67385 E (+/-0.00001), V = 12.44, B - V = +0.10, U - B = -0.03. The amplitudes are ΔV = 1.10, Δ(B - V) = 0.34, Δ(U - B) = 0.21. Skewness of light curve, ɛ = 0.14. These values confirm that the star is an RR Lyrae variable.
