DASO Circular No. 216 Issued: 2009 May 17, 15:40 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 identifications of Herschel and Planck on CBET 213, 214 and 215 were based on the pre-launch predicted trajectory. These predictions were not sufficient to correctly identify which object is which. An updated trajectory is now available for Planck. The astrometry published on CBET 213, 214 and 215 is being retracted. This CBET contains the astrometry (some of which appeared on the afore-mentioned circulars) for Planck. Planck performed a course correction between the first two sets of observations.
