                    Transit start, center and end times are in coordinated universal time (UTC).
                
                
                
                    If the option above is checked, only potentially fully or partially visible transits are shown. For a fully visible transit, the target is higher than 15° above the horizon for the entire duration (while the Sun is lower than 12° below the horizon). For a partially visible transit (highlighted in reddish), the above conditions are only met for the start, middle or end time of the transit.
