Vorticity of Granular Flows from NST Observations

We use observations taken with the New Solar Telescope (NST) at Big Bear Solar Observatory, the world largest solar optical telescope with diffraction limited spatial resolution of 0.06 arc seconds, to study vorticity of granular flows in quiet Sun areas. We employ sequence of images observed with TiO (705.7 nm) filter with time cadence of 30 seconds. The atmospheric seeing effects were removed using speckle-reconstruction technique. We compare vorticity of granular flows and intergranular vortices, and discuss our findings in the framework of surface (turbulent) dynamo.
