- Draw attention to work undertaken by IT services to support research needs of the solar physics community
- Publicise work on work investigating the dynamics generated by the solar global oscillations
- Improve understanding of solar physics
- Network with the solar physics community and understand some of the research computing needs
The conference opened with a discussion of wave coupling across the range of scale heights in the solar atmosphere and discussed the influence of magnetic field structures in opening windows channelling energy through the solar atmosphere. We hear how coupling was guided by 4 principles.
- The ramp effect - magnetoacoustic portal effect from inclined magnetic field
- Fast/slow mode wave conversion (Alfven speed matches acoustic wave speed)
- Fast wave reflection (horizontal wave speed same as acoustic wave speed)
- Fast/alfven mode conversion
These topics are discussed in the following references
- Multi-height Scattering Phase Shifts From Sunspots And Phase Differences Between Photospheric Heights With SDO/HMI and AIA Data
- Revealing the nature of magnetic shadows with 3D MHD simulations
- Three-dimensional numerical simulations of fast-to-Alfv́enonversion in sunspots
- Magnetohydrodynamic waves driven by p-modes
A discussion with Mats revealed a preference for the xeon-phi over omnipath for running large models using codes such as Bifrost. I also heard about the Bifrost implementation for handling boundaries using the method of characteristics for open end solutions.

We also enjoyed a morning boat trip to observe the sunrise, what a fitting way to start another full day of solar physics.
Robertus provided an overview of MHD waves in localised magnetic structures. He started with an overview of models of the solar atmosphere and described how they have evolved as our knowledge has increased with improving observational, theoretical and computational understanding.
DKIST solar telescope will be the largest in the world using adaptive optics to provide detailed imagery of the sun. We heard that it would have a 20km spatial resolution or 0.03" resolution at 500nm or 0.08" at 1.6micron. Operations are expected to start in December 2019.
Bhola Dwivedi from Banares Hindu University closed the conference
Man-Mahal observatory which I visited on my final day in Varanasi.
