1 Otero, Sebastian Alberto J-K= 1.59; B-V= 1.56. ASAS-3 magnitudes contaminated by GI Tau (V= 12.3 - 14.7; sep. 13"). Variability of GK Tau dominates in the combined light curve as can be seen comparing ASAS data with CRTS data for each of the two variables.
2 GCVS Team VB A (B = GI Tau, 13", 329deg). There are quasisinusoidal light variations with P = 4.6d [F.J.Vrba, A.E.Rydgren, D.S.Zak, P.F.Chugainov, N.I.Shakhovskaya, BAAS 16, N4, 998, 1984.]. Connected with a small bright arc-shaped nebula.
