An RAS Specialist Discussion Meeting organised by Mykola Gordovskyy(Manchester), James McLaughlin (Northumbria), Sarah Matthews(MSSL/UCL), Sergei Zharkov (Hull)Contact: Mykola.Gordovskyy@manchester.ac.uk
The structure of flaring atmospheres is determined by the magnetic fields and flows in the chromosphere and photosphere below. Solar flares, in turn, strongly affect the lower atmosphere, resulting in a wide range of flare-related effects with very complex dynamics. Interpreting these effects is essential for understanding magnetic energy build-up and release, as well as the topology and evolution of the coronal magnetic fields in solar flares. The aim of the meeting is to discuss flare-related phenomena in the lower atmosphere in the context of recent observations by Hinode, IRIS, SDO and SST, and future opportunities offered by DKIST. In particular, we will discuss:
- the photospheric magnetic field and its fine structure in flaring active regions,
- various types of helioseismic response in flares, and
- the small-scale structure and oscillations of the chromosphere during solar flares. 1000-1020 Registration and Tea/Coffee
