cds-question@unistra.frnovaeastrophysical-masersradio-astronomyinterferometryWe present multi-epoch observations with the VLBA of SiO maser emission in the v=1, J=1-0 transition at 43GHz from the remnant of the red nova V838 Mon. We model the positions of maser spots to derive a parallax of 0.166+/-0.060mas. Combining this parallax with other distance information results in a distance of 5.6+/-0.5kpc, which agrees with an independent geometric distance of 6.1+/-0.6kpc from modeling polarimetry images of V838 Mon's light echo. Combining these results, and including a weakly constraining Gaia DR2 parallax, yields a best estimate of distance of 5.9+/-0.4kpc. The maser spots are located close to the peaks of continuum at ~225GHz and SiO J=5-4 thermal emission detected with ALMA. The proper motion of V838 Mon confirms its membership in a small open cluster in the Outer spiral arm of the Milky Way.2020A&A...638A..17Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/638/A17CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/434/1107 : UBV(RI)c photometry of stars around V838 Mon (Munari+, 2005)J/A+A/532/A138 : V838 Mon spectrum in 2009 (Tylenda+, 2011)J/AZh/84/147 : Light curves of V838 Mon and V4332 Sgr (Goranskii+, 2007)J/ApJ/598/L43 : Polarimetry of V838 Mon and stars around (Wisniewski+, 2003)J/PAZh/28/764 : UBVR photometry of Nova Mon 2002 (V838 Mon) (Goranskii+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/638/A17https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/638/A17http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/638/A17https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/638/A17https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/638/A17http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/638/A17GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/638/A17/list (List of fits datacubes)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/638/A17/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/638/A17/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/638/A17/list?GETtext/xml+votable180.050000true106.02009-3.84740.0055555555555555566/22082https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/638/A17?format=asciiRadiodefaultJ/A+A/638/A17/table1VLBA observed epochsrecnoRecord number assigned by the VizieR team.
