WISA 2023

The first Waves and Instabilities in the Solar Atmosphere (WISA) meeting will be held in June 20 - 23, 2023 at Northumbria University, Newcastle, UK.

The WISA meeting provides a platform for the international solar physics community, whose interests lie in magnetohydrodynamic (MHD) waves in the solar atmosphere, to exchange ideas and to foster collaboration and knowledge transfer. The aim of the meeting is to exchange new results on observations, data analysis, and theoretical and numerical modelling of MHD waves and instabilities. During the meeting, current open questions and future directions will be discussed, with focus on recent results from Parker Solar Probe and Solar Orbiter, and the imminent opportunities arising from the Daniel K. Inouye Solar Telescope (DKIST).

This meeting will focus on four key topics, namely:

• Wave generation, energy transport, dissipation and heating

• Instabilities

• Seismology of solar and stellar atmospheres

• Novel diagnostic techniques and forward modelling

The meeting will include a full day workshop (half-day theory + half-day tutorials) on novel diagnostic techniques. We will have tutorials on:

• MHD spectroscopy (LEGOLAS code), given by Niels Claes (KU Leuven)

• Fourier and wavelet analysis (WOW code), given by Frédéric Auchère (IAS)

• Motion magnification, given by Tim Duckenfield (Northumbria U)

• Sonification of astronomical data, given by Christopher Harrison (Newcastle U) and James Trayford (Portsmouth U)

WISA is the 1st meeting of what is planned to be an annual occurrence, taking over from the successful series of meetings called BUKS. The BUKS meetings, started in 2009, were a series of open and informal workshops on MHD waves and Seismology of the Solar Atmosphere started by institutes in Belgium, UK and Spain (BUKS). Although BUKS welcomed participants from any country a change in name was decided to make this inclusivity more explicit.
