The FK4 Equinox from Meridian Observations of Minor Planets
Abstract
Minor planets 1 (Ceres), 2 (Pallas), 3 (Juno), and 4 (Vesta) were observed during a five and a half year period with the Naval Observatory's 7-inch transit circle at El Leoncito, Argentina. From 1043 observations in right ascension and 1020 in declination the correction to the FK4 equinox was found to be +0".634 plus or minus 0".155, in good agreement With other determinations of this quantity. This successful equinox determination from a relatively short observing period was possible because the large number of clear nights at El Leoncito permitted many observations to be taken.
