Notes. Used positions are always within a month of event epoch. Error estimates come from the dispersion (standard deviation) of values from the observations. Mean error of (RA, Dec) solutions and average number of UCAC2 reference stars are given. The UCAC2-based candidate star positions were zero-point-corrected toward ICRS using averaged UCAC2 minus ICRF position offsets ( cos = -12  8 mas;  = -5  7 mas) of five ICRF quasars nearby Pluto present coordinates (see Assafin et al. 2005). For the 2006 June 12 event, useful CCD observations were only acquired in April 2007, but the final position is at the event epoch, as proper motions (  = -10.6 mas yr^-1,  = -12.9 mas yr^-1) were applied for this UCAC2 star. The 2008 August 25 event star was observed with the 1.6 m P&E LNA telescope (FOV of 5  sizes and pixel scale of 0 17). Actually, 2005 July 11 refers to a stellar occultation by Charon.
