We present a short account of ongoing reduction and interpretation of the observations of HL Tau 76 obtained during the WET campaign of 1996. We also included in the discussion the results of several single-site observations, obtained between 1989 and 1996. In introduction, we give a short synopsis of works about the same star, published by several authors from 1968 to 1972: the comparison of those results with more recent observations gives a new and intriguing insight into the behavior of this extremely interesting object.
