GCVS data:
Epoch 2000: ra = 110.434, dec = 69.671
Variability type: CWA
Spectral type: C0,1-C3,2e(K0-R0)
GCVS remarks:
[A/H] = +0.9:. P var. Min = 2417610.1 + 22.187d*E (1908 - 1917), Min = 2421315.3 + 22.121d*E (1917 - 1922), Min = 2423195.6 + 22.217d*E (1922 - 1931), Min = 2426350.4 + 22.138d*E (1931 - 1951), Min = 2433700.2 + 22.162d*E (1951 - 1961), Min = 2437356.9 + 22.055d*E (1961 - 1965) [03243]. Unusual variable. The shape of the light curve varies. Before 1964 broad maxima and sharp minima were observed; Delta(m) varied by the factor of 2, with a possible cycle 5.1a [03241]. After 1964 - 1966 Delta(m) decreased abruptly (to 0.4m - 0.1m and smaller), the light curve became symmetric; the mean light varies in the range of 0.3m B. The period varies irregularly in the interval 19.4d - 23.5d. Groups of oscillations are observed to replace one another, with phase shifts up to 0.5p [04206]. Unusual spectrum with intense CN and weak C2 bands.
