This Working Group will focus on science cases addressing magnetoconvection processes in active regions and the quiet Sun and their influence on the upper solar atmosphere, using measurements from various Solar Orbiter instruments, particularly PHI, and also coordinated observations with ground-based telescopes/near-Earth space assets.

Both the Solar Orbiter and ground-based telescope communities are invited to participate in this WG, as are theorists and simulation experts interested in confronting their ideas with state-of-the-art measurements.

The objective is to better exploit the unique capabilities offered by Solar Orbiter for magnetoconvection studies:

  • A complete suite of remote-sensing instruments for seamless coverage of the solar atmosphere at high spatial and temporal resolution

  • A different vantage point allowing for magnetic and dynamic stereoscopy

  • Periods of reduced rotation with respect to the Sun allowing for longer continuous observations of targets with smaller projection effects

In particular, this WG will address the following main topics in the Solar Orbiter Science Activity Plan:

  • Properties of fields in active regions, network and internetwork

  • 3D geometry of convective and magnetic features

  • Internal structuring of magnetic features

  • Brightness of magnetic features

  • Long-term behavior of active regions, network and internetwork

  • Flux emergence

  • Flux cancellation

  • Flux transport

  • Magnetohydrodynamic waves

All these science questions have implications for the magnetic coupling of the solar atmosphere and atmospheric heating, so close interactions with other RSSWGs will be sought.
