Observational Evidence for the Hanle and Magneto-Optical Effects in the Polarization of the Mg II h & k Lines Observed by CLASP2

CLASP2 (Chromospheric LAyer Spectro-Polarimeter)
- Demonstration of the UV spectro-polarimetery as a diagnostic tool of magnetic fields in upper chromosphere
- High-precision (<0.1%) spectro-polarimetry across the Mg II h & k around 280 nm
- Aim at measuring magnetic field in top chromosphere
- International NASA sounding rocket program
- Refitted the instrument: CLASP (Lya @ 122 nm) → CLASP2)
- Launched at White Sands Missile Range, NM, USA on April 11, 2019
