On the Magnetic Nature of Solar Exploding Granules
Abstract
We report on spectropolarimetric observations acquired by the imaging magnetograph SUNRISE/IMaX at high spatial 0.''3 and temporal (31.5 s) resolution during the first science flight of this balloon-borne solar observatory. We describe the photospheric evolution of an exploding granule observed in the quiet Sun. This granule is cospatial with a magnetic flux emergence event occurring at mesogranular scales (up to ∼12 Mm2 area). Using a modified version of the SIR code, we show that we can estimate the longitudinal field also in the presence of a residual cross-talk in these IMaX longitudinal measurements. We determine the magnetic flux content of the structure (∼3 ×1018 Mx), which appears to have a multipolar configuration, and discuss the origin of such flux emergence events.
