Abstract: In this paper, we present 112 new CCD astrometric positions of Nereid, the second and faint satellite of Neptune (mv ~= 19). We observed this small satellite in the 2006-2007 period with the 1 and 2.16-m telescopes of Xinglong Station near Beijing, both equipped with large CCD detectors of 1340 ? 1300 and 2080 ? 2048 pixels, respectively. The high density and highly accurate star catalogue UCAC2 was used in the reduction so that a classical astrometric calibration method was applied. We have shown that our observations of Nereid appear to be of equal or higher precision (? ~= 0.2 arcsec) than most of the recent CCD ones. The data are available in electronic form as Supplementary Material to the online version of the paper on Blackwell Synergy, at the CDS via Anonymous FTP to http://cdsarc.u-stasbg.fr or via http://cdsweb.u-strasbg.fr/Abstract.html.
