ASTROMETRIC OBSERVATIONS OF THE MARTIAN SATELLITES FROM TARIJA, 1988

Abstract

141 topocentric positions of Phobos and 113 of Deimos are presented as obtained from photographic observations performed during August and November 1988 at the 60-cm reflector of the Tarija Observatory, Bolivia.

I.Introduction

A set of photographic observations of the Martian system was made in the frame of the ground-based observing project for the Phobos mission at the Tarija Observatory (TO), Bolivia, during the opposition of Mars, between August and November 1988.

Most of plates were rapidly processed at the same time. Reduction of the plates was done by such a method using the measures on the reference stars only to determine a required orientation angle and scale factor. The planet -relative coordinates of Phobos and Deimos had been transmitted to orbit centres in due course by 15 November 1988.

However, because the Mars' images are overexposed, the deduced planet- satellite coordinates suffer from the magnitude error and systematic errors due to estimation of the position of the planetary center. With this in mind we have rereduced the observations in "full mode" in order to determine equatorial coordinates of the Martian satellites.

II.Observations

The observations were made with the 60-cm Cassegrain telescope. The plate scale is 27.5 arcsec/mm, giving the 6 x 6 cm field of about 30 x 30 arcmin. During the interval, August - November 1988, more than 200 usable exposures of the Martian system were taken on ORWO ZU-21 and NP-27 plates with no filter or other magnitude compensation making one to six exposures on each plate. When multiple exposures were taken on a single plate the telescope was shifted in declination or right ascension by a small amount between exposures. The exposure time varied from 20 to 50 seconds, depending on the meteorological conditions. The time of observation was recorded to an accuracy of 0.5 s with the marine chronometer.

III.Astrometric processing and results

With the observations having been carried out, we come back to the Main Astronomical Observatory (MAO) in Kyiv and started a new examination of the plates. We found that some faint images of satellites previously not measured with the ASCORECORD 3DP measuring machine at the TO could be measured with the ASCOREMAT measuring machine at the MAO. Therefore several plates were remeasured. In addition, another plates containing the faint measurable images were also measured.

In order to eliminate the systematic errors of setting, four sets of measures of each image on the plate were made in different positions of reversing prism. The means of four such measures were taken as the measures of the plate.

It was often the case that a given satellite was embedded in the planetary halo or diffraction spike. So setting of cross-wires on such images, especially of hardly visible ones are rather doubtful.

In processing the plates, each exposure and each measurement were treated separately. Measures of Mars and its satellite(s) were reduced by the method of plate constants.

The reference star positions were taken from a catalogue specially prepared for this project by H.Potter at the Pulkovo Observatory. The catalogue is based upon the FK5/J2000 version of the FOCAT-S star catalogue and has a mean epoch of 1987. The catalogue provides an average density of 23 stars per square degree and a magnitude range between 6 -11.5 within one degree of Mars' apparent path from July through November 1988.

The positions of satellites, resulting from the plate reduction, have been compared with the JPL DE403 ephemerides. A number of them were found to have residuals greater than 1.25 arcsec and these have been rejected. The nonrejected positions derived from the repeated measurements of a given exposure were united. The positions of Mars were excluded from the subsequent discussion.

The astrometric positions of Phobos and Deimos remained after trying are given in Table 1 and are plotted on Fig. 1.

For each position are given the epoch of observation (the UTC mid-exposure epoch), right ascension and declination referred to the standard equator and equinox of J2000, the plate number, the exposure number, the number of reference stars, the rms star residuals for RA and Dec (the standard deviations of the plate solutions in RA and Dec), the emulsion, codes for observer and measuring machine (identified at the end of the table).

IY.Conclusion

We presented above 254 observations of Martian satellites. They are distributed between 22 nights in four months. The reported coordinates of satellites in the combination with accurate ephemereis of Mars may yield more reliable data than measured planet-satellites coordinates.
