SUMMARY:The fine scales of solar chromospheric flares - Lyndsay Fletcher (
 Glasgow)
DTSTART:20251201T160000Z

CONTACT:Roger Dufresne
DESCRIPTION:A solar flare is an intense but short-lived release of energy 
 from the Sun's magnetically-dominated atmosphere\, resulting in the accele
 ration of non-thermal particles\, plasma heating\, and radiation across th
 e entire electromagnetic spectrum. Most energy released is radiated by the
  solar chromosphere\, giving rise to bright\, highly structured 'footpoint
 s' and 'ribbons' of chromospheric emission. The big picture of a solar fla
 re\, and the significance of flare ribbons in the global reconnection scen
 ario\, is well established\, but high-resolution observations show fine sp
 atial\, temporal and spectral structure which can be probed to further exp
 lore flare physics. In this talk I will overview the basic framework of a 
 solar flare and its development in the solar chromosphere\, highlighting s
 ome examples of how fine scales are being used to investigate energy relea
 se and transport. I will focus on results from the IRIS spacecraft in the 
 UV\, and a newly-opened window on flares in the thermal infrared.
