Predicted (solid lines) and observed (dashed lines) shadow paths for the 2003 VS2 stellar occultation on 2019 October 22 through Gaia DR2 source 3449076721168026496. The prediction was made updating the JPL #30 ephemeris with the offsets obtained with data from the Liverpool 2-m Telescope in the Roque de los Muchachos Observatory (La Palma, Spain). The green line represents the middle of the shadow path and the blue lines indicate the limits of the shadow (width of the shadow path is 479 km, from JPL). The observing sites involved in the event are also marked: in green, the ones that reported a positive detection; in red, those that reported a negative detection; and, in blue, those that could not observe due to bad weather or technical problems, see Tables 3, 4, and A.1.
