Notes:

1-σ uncertainties on these UT times are of the order of an hour.
These times are computed for the best current orbit solution, assuming object radii of 125 km for Sila and 118 km for Nunam.
"Superior" events are when Sila appears in front of Nunam and "Inferior" events are when Nunam is in front of Sila.
Links provide a schematic diagram of each event in encapsulated Postscript format showing the motion of Nunam relative to Sila and the location of the shadow of the foreground object at the distance of the more distant object (scale in km relative to the primary center). Links also provide a model lightcurve of each event as an EPS plot and as ascii data. These models assume spherical shapes and Lambertian scattering behavior.
