Spectral type: A5-F5
GCVS remarks:
[Fe/H] = -1.2. P var. Max = 2417201.241 + 0.4665878*E - 0.000107d*10**(-6)*E**2 (JD2414000 - 35000) [02550]; Max = 2438562.796 + 0.466570d*E (JD2434000 - 39800); Max = 2440445.789 + 0.466497d*E (JD2439800 - 41000) [06237]; Max = 2441453.3856 + 0.4664731d*E (JD2441000 - 42500) [07424]; Max = 2443028.641 + 0.466438d*E (JD2442500 - 43800) [09101]; Max = 2444142.650 + 0.466649d*E (JD2443800 - 44200) [09102]; since JD2444100 - see Table. Besides that the star has a strongly expressed Blazhko effect; the period of Blazhko effect varies, too [07424, 07425]. 0.13P <= M - m <= 0.22P; 0.90m <= A(B) <= 1.70m, 0.70m <= A(B) <= 1.30m; -0.05P < O - C < +0.05; Max A = 2417025.5 + 57.401d*E (JD2417000 - 38500); Max A = 2438881.7 + 58.387d*E (since JD2438500).[09103]. After JD2444000 Blazhko effect period probably decreased to 56.3d [09102].
