Ephemeris from Miriade for the date of occultation and geocenter frame. For more specific ephemeris please use the documentation of Miriade.
(3749) Balam is a system triple. At this date no orbit solution was obtained by the lack of astrometrical observations. Rather than predict satellite's path, potential observers should try to observe until a distance of 300 kilometers (assuming this number take into account the accuracy position of the primary and the occulted star).
