Two stellaroccultations by Lucina have been observed so far, in 1982 and 1989. During the first event, a possible small satellite with an estimated 5.7 km diameter was detected at a distance of 1,600 km from 146 Lucina. A 1992 search using a CCD failed to discover a satellite larger than 0.6 km, although it may have been obscured by occultation mask. Further evidence for a satellite emerged in 2003, this time based on astrometric measurements.
