Observational evidence for a hot gaseous Galactic coronaGalactic absorption features observed in high-dispersion far-UV spectra of two Large Magellanic Cloud (LMC) stars obtained with the IUE satellite are discussed. The stars observed were HD 38268 (OB + WN5) and HD 38282 (WN6), which lie at a distance of about 55 kpc and in the galactic direction corresponding to a latitude of about -32 deg and a longitude of about 280 deg. The line of sight to these stars passes through the disk and halo of the Milky Way and the halo and disk of the LMC. Evidence is presented for the existence of a hot (somewhat below 1 million K), low-density (about 0.001 H atom per cu cm) Galactic corona.
