« Previous Version 6 Next » Detect and characterise waves in closed and open structures (e.g. De Pontieu et al., 2007), looking for signatures of their dissipation in the transition region and low corona, with a corresponding evaluation of the energy released to heat the solar plasma.


Targets: AR (also closed loops in QS?), on-disk and also off-limb (for spicules).

Maybe divide this objective per target?

      • Measurement of the solar wind outflow velocity gradient in the outer corona, to localise regions of energy deposition, via Doppler dimming of the HI Lyα intensity in the field of view 1.5-2.9 degrees. Measurement of the magnetic field topology through the global corona configuration. Measurements of the brightness fluctuation spectra.
