| Abstract: |
Many features of solar surface turbulence, like the supergranulation,
are still poorly understood.We use long time series of images taken by the Solar Optical
Telescope on board the Hinode satellite to determine the velocity fields. The dynamics in
the subgranulation range can be investigated with unprecedented precision thanks to the
absence of seeing effects and the use of the MTF of SOT for correcting the spectra. The
first MOF/CALAS/Pic–du–Midi results are also shown. |
