Occultation by 2002WC19 (2018-12-30)

Information about the map:

• The straight and continue lines are the shadow limits considering the estimated radius; when the shadow crosses the Earth's surface, the path is projected on the Earth;
• Each blue dot is spaced by one minute and the big blue dot corresponds to the nominal occultation time (which is the geocentric closest approach);
• The arrow shows the direction of the shadow motion;
• The 1-σ precision along the path is represented by the red dotted line;
• The star G* and RP* are the G (from Gaia) and RP (red photometer from GaiaDR2) magnitudes, normalized to a body moving at 20km/s in order to enhance very slow events;
• The body offset is at the upper right corner, if JPL ephemeris is used;
• Areas in dark grey correspond to full night (Sun elevation below -18 degrees) and areas in light grey correspond to twilight (Sun elevation between -18 and 0 degrees) while daytime is in white;
• Be careful, the dates are from the moment of the event in Universal Time, the night of the event may begin at the date before.
