^(*) The blue dots are separated by a one-minute interval and the big blue dot corresponds to the nominal occultation time (which is the geocentric closest approach).

⁽¹⁾ Some asteroids may have differents measures concerning their binary characteristics, they are summed up here.

For declination above -25 °, Pan-STARRS survey is displayed by default whereas below -25 °, DSS is displayed.

Observation advice
To be able to observe the asteroid satellite, we recommend, if the satellite is in the path of the primary body, that you start recording your observations preferentially around 3min beforehand.
Interactive map legend
The large blue line represents the centrality of the nominal prediction. The thin dotted blue lines represent the body's limits of the nominal prediction. Red lines show the region where the satellite can be. The white area represents the daylight part on Earth and the blue area represents the region on Earth where the object is not visible. The shadow at nominal time is displayed, the brighter part represents the uncertainty in the body's radius. The Sun symbol indicates the place where the Sun is at the zenith at the nominal time. The star symbol indicates the place where the occulted star is at the zenith at the nominal time. Grey zone represents the night area.
By clicking on one place, you will have an infobox with :

• Coordinates: Longitude and latitude;
• ρ and Δd: Impact parameter (i.e. projected distance to the central line) and σ distance; Δd is (ρ-r)/σ_d where r is the object radius and σ_d is the uncertainty in distance;
• Mid time: Mid time of the occultation at the selected place;
• Expected duration (main body): Expected duration of the occultation of the main body at the selected place;
• Max expected duration (satellite): Expected maximum duration of the occultation of the satellite at the selected place, the two values corresponds to the two possibles solutions for the satellite diameter;
• Object elevation: Object's elevation above the horizon at the selected place at the mid time;
• Sun and Moon elevation: Sun's and Moon's elevation above the horizon at the selected place at the mid time;

Once the place selected, the shadow at mid-time of the occultation for the location is displayed. The chord for your location appears in as a green dotted line. Sun and star symbols as well as the night area and area where the star is not visible are ajusted at the mid-time of your location.
