| Abstract | A stellar occultation by the extreme large-perihelion trans-Neptunian object (541132) Leleākūhonua (also known by the provisional designation of 2015 TG₃₈₇) was predicted by the Lucky Star project and observed with the Research and Education Collaborative Occultation Network on 2018 October 20 UT. A single detection and a nearby nondetection provide constraints for the size and albedo. When a circular profile is assumed, the radius is r=110⁺¹⁴₋₁₀ km, corresponding to a geometric albedo Pv=0.21⁺⁰⋅⁰³₋₀.₀₅, for an adopted absolute magnitude of Hv = 5.6, typical of other objects in dynamically similar orbits. The occultation also provides a high-precision astrometric constraint. |
