Abstract

The classical Ertel-Struve vertical circle of the Pulkovo Observatory was astablished at the Kislovodsk Mount Station. From 1984 to 1989 we have obtained 566 declinations of the Sun, 230 of Mercury, 413 of Venus, and 207 of Mars. Observations were visual, and the reductions were differential in the FK5 system. Only day-time observations of reference stars were used.
