Description:
The immediate objective of these observations is the measurement of magnetic fields in prominences, solar tornados and/or spicules. We propose to exploit the excellent spectro-polarimetric capabilities of THEMIS for measurements of the magnetic field vector in prominences, solar tornadoes and spicules employing the inversions of the He D3 line. These phenomena represent unique examples of the small-scale coupling between magnetic field and plasma in environments with distinct dynamical behaviour. As such they represent key study-cases for deepening of our understanding of the Sun. SOT is used to give context to EIS and ease co-alignment with THEMIS.
