DASO Circular No. 274 Issued: 2009 July 31, 13:34 UT The DISTANT ARTIFICIAL SATELLITES OBSERVATION (DASO) Circulars are a private publication by staff of the Minor Planet Center and are intended to disseminate astrometric observations of distant artificial satellites. Editor: Gareth V. Williams (gwilliams@cfa.harvard.edu) Astrometry submissions to mpc@cfa.harvard.edu (Subject line = "ART SAT") The nominal geocentric orbit for 9O0DC57 (Incl. = 42 deg [to equator], a ~ 73000 km, e = 0.76, P = 2.3 days) indicates that the orbit is stable for +/- 100 days from the present. Ephemerides for 9O0DC57 are available on the Distant Artificial Satellites Observation page (http://www.cfa.harvard.edu/iau/SpaceJunk/SpaceJunk.html).
