Minor planets 1 Ceres, 2 Pallas, 3 Juno, and 4 Vesta were observed during a five and a half year period with the Naval Observatorys 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.
