Asteroid Cuyo observing geometries during the light curve observations. The graphs display different quantities as a function of time (in years). Top two panels: positions of the object in the ecliptic coordinate system, latitude and longitude, as observed from Earth. Bottom two panels: phase angle (angle between the positions of Earth and Sun as observed from the target), and geocentric distance to the target. Optical light curve data from NTT are marked with filled black circles, with light curve data from supporting campaigns marked with filled green circles. Red squares represent the additional light curve data available. The black continuous line is the object’s observational ephemeris.
