Observations of the Sun with a modified Danjon astrolabe at 30° and 60° zenith distances are beeing carried out since 1990 at Santiago, Chile. Here are presented the results in right ascension, parameter Y and apparent semidiameter obtained during the period 1995-1997. These results and those obtained in former years are available in electronic form. The differences astrolabe minus ephemeris in alpha and semidiameter are briefly discussed.
