 abstract of observational proposal
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-
We thus need a long observing period to get a chance to get the required
