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.
