Positions of Mars obtained in Nikolaev Astronomical Observatory

The mean period of observations in opposition was 156 days. The orbits of Mars and Earth were covered 7.3 and 3.8 times respectively.

After defining more exactly some computational elements and the planet's phase, 441 positions were obtained in ICRS system. Coordinates of reference stars were taken from Hipparcos and Tycho catalogues, and their proper motions were taken from the ACTRC catalogue. The standard errors in right ascension and declination are ±0."21 and ±0."22 respectively, in accordance with accuracy estimations of the Institute of Applied Astronomy of the Russian Academy of Science.
