Map of the ground track of our latest prediction update, based on astrometry obtained at the 2 m LT on La Palma. A spherical diameter of D = 285 km was used for 2003 UY₁₁₇ for the predicted shadow path width (blue lines) plotted in this figure. The map also displays the sites where the occultation was observed, with blue markers indicating a positive detection and red ones indicating a negative detection (i.e., a “miss”). Negative observations reported from Belgium and England, which were located within the uncertainty of the original nominal prediction, are outside this map. Map credit: OpenStreetMap.
