J/A+AS/132/195      Astrolabe observations of the Sun in 1995-1997 (Noel 1998)

Observations of the Sun with the astrolabe of Santiago: 1995-1997 Noel F. <Astron. Astrophys. Suppl. Ser. 132, 195 (1998)> =1998A&AS..132..195N (SIMBAD/NED BibCode)
ADC_Keywords: Sun; Positional data Keywords: astrometry - Sun: general Abstract: Observations of the Sun with a modified Danjon astrolabe at 30° and 60° zenith distances have been 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 for mer years are available in electronic form. The differences astrolabe minus ephemeris in α and semidiameter are briefly discussed. File Summary:
