1 GCVS Team ADS 12259 B (A 7.5m; B 20", 14deg); d = 0.032P. P increases (see also [R.Szafraniec, SAC N29, 106, 1958., M.E.Baldwin, JRAS Can 73, N5, 320-324, 1979.]). Before JD2435600 Min = 2428023.550 + 3.390842d*E. Halpha emission observed at Max light [M.Plavec, R.S.Polidan, UCLA Astron. Papers 15, N21, 1976.]. The shape of the light curve and d apparently vary. Delta(m) probably decreases [R.Diethelm, K.Locher, H.Peter, BBSAG Bull N38, 1978.].
