Notes. In entry order, the above samples correspond to the predictions for 2002 TX300 (October 2009), Varuna (February 2010), Eris (November 2010), 2003 AZ84 (January 2011), Makemake (April 2011), and Quaoar (May 2011), respectively. Prediction tables list event date and instant (UTC), the ICRS (J2000) star coordinates at occultation, the closest apparent distance between star and TNO (C/A), the position angle (P/A) of the shadow across the Earth (counter-clockwise, zero at north), the velocity in km s-1, the distance (D) to the Earth (AU), R, J, H, and K star magnitudes normalized to a reference shadow velocity (v) of 20 km s-1 (50.0 means no magnitude available), longitude (λ) of the sub-solar point, local solar time (LST), (Δeαeδ) JPL ephemeris offsets in (α,δ) for the central instant (see Sect. 5), catalog cross-identification (uc = UCAC2, 2m = 2MASS, fs = field star), proper motion existence and multiplicity flags (see Sect. 3), estimated star-catalog position errors (Eα,Eδ), and proper motions (μα,μδ). Positive/negative v means, respectively, prograde/retrograde velocities, that is TNO’s geocentric right ascension is increasing/decreasing, respectively. The complete table sets of 2008/2009–2015 predictions for Eris, Haumea, Ixion, Makemake, Orcus, Quaoar, Sedna, Varuna, 2002 TX300, and 2003 AZ84 are available in electronic form at the CDS. In the electronic version, in addition to the star positions, we provide the TNO estimated coordinates (with ephemeris offsets applied) at occultation instant.
