Abstract

The Hinode satellite observations revealed that solar surface magneto-convection is more active than previously expected. Hinode helped enhance our knowledge of small-scale structures with its high temporal and spatial resolution data. In particular, the granular element structure of the magnetic field was observed, and the related phenomena have been widely investigated in the past decade since its launch. In this paper, we examine the observational results of such small-scale magneto-convection fields using the Hinode satellite data and propose future tasks in the following 10 years.
