DESCRIPTION:Speakers: Gherardo Valori (MPS - Max Planck Institute for Sola
 r System Research)\nSpectropolarimetric reconstructions of the photospheri
 c vector magnetic field are intrinsically limited by the 180-degree-ambigu
 ity in the orientation of the transverse component.  So far\, the removal 
 of such an ambiguity has required assumptions about the properties of the 
 photospheric field\, which makes disambiguation methods model-dependent.\n
 \nThe successful launch and operation of Solar Orbiter have made the remov
 al of the 180-ambiguity possible solely using observations of the same loc
 ation on the Sun obtained from two different vantage points. To that purpo
 se\, the Stereoscopic Disambiguation Method was recently developed and suc
 cessfully tested on numerical simulations.\n\nHere we present the first ap
 plication of the SDM to data obtained by the High Resolution Telescope (HR
 T) onboard Solar Orbiter during the March 2022 campaign\, when the angle w
 ith Earth was 27 degrees. The method is successfully applied to remove the
  ambiguity in the transverse component of the HRT vector magnetogram solel
 y using observations (from HRT and from the Helioseismic and Magnetic Imag
 er-HMI)\, for the first time.\n\nThe SDM is proven to provide observation-
 only disambiguated vector magnetograms that are spatially homogeneous and 
 consistent.\nWhile we present here an application combining PHI with HMI d
 ata\, the same method can be applied to magnetic information from Solar Or
 biter together with any Earth-bound observatory.\n\nhttps://meetings.aip.d
