RR Lyr light curve covering the pulsation cycle from ϕ = 0.57 to ϕ = 1.31. V magnitudes were measured with the G filter (490−580 nm) corresponding to the V photometric Johnson-Cousins bandwidth (490−590 nm) on a Schmidt-Cassegrain 5′′ telescope. Observations were made between June 10 and 15, 2013, when the Blazhko phase was in the interval ψ = 0.74−0.87. Dashed lines show the phases around which the three different emissions appear within the Hα profile.
