Description:
    A program of solar observations at 30deg and 60deg zenith distance is
    in progress since 1990 with the modified Danjon astrolabe of Santiago.
    Results in right ascension, parameter Y and apparent semi-diameter of
    the Sun obtained with the astrolabe at both zenith distances during
    1994, are available.
