The parallax is 0.330 ± 0.018 mas, corresponding to a distance of ${3.03}_{-0.16}^{+0.17}$ kpc. This locates G034.43+0.24 near the inner edge of the Sagittarius spiral arm and at one end of a linear distribution of massive young stars that cross nearly the full width of the arm. The measured three-dimensional motion of G034.43+0.24 indicates a near-circular Galactic orbit. The water masers display arc-like distributions, possibly bow shocks, associated with winds from one or more massive young stars.STAMPAenArticle10.3847/1538-4357/acc52a2-s2.0-85160090616https://api.elsevier.com/content/abstract/scopus_id/85160090616https://iopscience.iop.org/article/10.3847/1538-4357/acc52a2023ApJ...949...10MFIS/05 - ASTRONOMIA E ASTROFISICA
