1 GCVS Team Usually varies within the limits 4.4m - 5.2m V. In November 1945 the peculiar decrease of brightness began lasting for 165d and in September 1946 the star reached the middle of the deepest minimum (JD2432070) lasting for 320d. Then the brightness began to increase symmetrically and by July 1947 the star attained its normal brightness [S.Gaposchkin, HB N919, 1949.]. Photographic magnitudes varied in the limits 5.4m - 8.3m. Spectrum description [W.W.Morgan, Ph.C.Keenan, H.A. ABT, J.W.Tapscott, ApJ 243, 894, 1981.].
