Abstract: On February 18 UT (19th local date), the brightest star occulted by a sizeable asteroid during 2018 occurred in eastern Australia. The star was \eta Ophiuchi = Sabik = HIP 84012 = WDS 17104-1544 = BU 1118AB, anearly equal binary. This article describes the special efforts needed to predict the path of the occultation by the primary star, the effort to observe the event from multiple remote stations, and the successful observations, with a good elliptical fit to the three positive chords.
