1 GCVS Team Min II 6.1. SB. In [G.C.Kilambi, IBVS N1024, 1975.] variations were noted with Delta(m) ~0.1m and P < 3h, presumably of DSCT type nature. Some sources give A3 for the spectral type. Shell spectrum was observed in May, 1975. Spectral lines were filled with emission and therefore weak, strong absorption in H and K CaII lines was present. Shell effects were not present in the spectra taken in 1971 - 1973 [W.R.Beardsley, M.W.King, IAU Circ N2890, 1975.].
