- The document summarizes data from the Sunrise balloon-borne solar observatory, which achieved high-resolution spectro-polarimetric observations of the solar atmosphere using instruments like IMaX and SUFI. - Preliminary data shown includes a map of the magnetic field vector and white-light images of the solar surface at resolutions as fine as 0.05 arcseconds (350 km). - The science goals are to study magnetoconvection at small scales, observe the formation of magnetic elements, and investigate phenomena in solar active regions like penumbral filaments.
