Abstract :
A superior mutual event of the Kuiper Belt binary system (79360) Sila–Nunam was observed over 15.47 h on UT 7/8 February 2013 by a coordinated effort at four different telescope facilities; it started ∼1.5 h earlier than anticipated, the duration was ∼9.5 h (about 10% longer than predicted), and was slightly less deep than predicted. It is the first full event observed for a comparably sized binary Kuiper Belt object. We provide predictions for future events refined by this and other partial mutual event observations obtained since the mutual event season began.
