cds-question@unistra.frasteroidsoccultationastrometryphotometryA stellar occultation by the extreme large-perihelion trans-Neptunian object (541132)-Leleakuhonua (also known by the provisional designation of 2015TG_387_) was predicted by the Lucky Star project and observed with the Research and Education Collaborative Occultation Network (RECON) 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_-10_^+14^km, corresponding to a geometric albedo p_V_=0.21_-0.05_^+0.03^, 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.2020AJ....159..230Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/159/230CatalogResearchIsServedByTAP VizieR generic servicerelated-toII/190 : IRAS Minor Planet Survey (IMPS) (Tedesco 1992)B/occ : Occultation lights curves (Herald+ 2016)I/345 : Gaia DR2 (Gaia Collaboration, 2018)J/other/CoSka/35.45 : Astrometry of minor planets in 2003 (Neslusan+, 2005)J/A+A/515/A32 : Pluto, Charon, Nix, Hydra occultations 2008-15 (Assafin+,2010)J/ApJS/189/336 : HST astrometry of TNOs (Benecchi+, 2010)J/A+A/532/A101 : Lunar occultations of 184 stellar sources (Richichi+, 2011)J/A+A/541/A142 : Prediction stellar occultations 2008-2015 (Assafin+, 2012)J/A+A/561/A37 : Prediction of stellar occultations 2012.5-2014 (Camargo+,2014)J/A+A/584/A96 : Observations of 50 TNOs and Centaurs (Desmars+, 2015)J/AJ/152/80 : Astrometry of Pluto & trans-Neptunian objects (Holman+, 2016)J/AJ/152/111 : A 2011-2013 survey of TNOs (Alexandersen+, 2016)J/AJ/152/221 : New extreme trans-Neptunian objects (Sheppard+, 2016)J/ApJS/236/18 : OSSOS.
