The goal is to investigate the physics of spicules type II through coordinated observations with Hinode and SST. We want to try to determine apparent velocities along the spicules/straws, whether these velocities are material motions and the thermodynamic evolution. We also want to get statistics on transversal motions. We will try to achieve the goals through very high resolution observations in three different Ca-H filters (continuum, inner wing, core), Ca-K filter (core) and H-alpha (various positions) from SST on La Palma and with Ca-H BFI and H-alpha from Hinode SOT and various lines with EIS. Limb pointing with SST is extremely challanging and demands very good seeing conditions and appropriate faculae close to the limb for AO- locking. We thus need a long observing period to get a chance to get the required conditions. |
