SUMMARY:David Long (MSSL): Probing the solar corona using global “EIT wav
 es"
TZID:Europe/London

DESCRIPTION:“EIT waves” are globally-propagating disturbances in the sola
 r corona that remain controversial almost twenty years since they were f
 irst observed by the Extreme ultraviolet Imaging Telescope (EIT) onboard
  the Solar and Heliospheric Observatory (SOHO). Although they were origi
 nally interpreted as waves\, this assumption has been challenged by oppo
 sing observations from different instruments and spacecraft. Many confli
 cting interpretations have therefore been proposed to explain the phenom
 enon. The high temporal and spatial resolution observations provided by 
 the Solar Dynamics Observatory (SDO) have revolutionised our understandi
 ng of these features and how they evolve through the solar corona. These
  observations have allowed the development of automated tracking algorit
 hms and better data-driven simulations\, which\, combined with detailed 
 case studies and statistical analysis of event databases\, are leading t
 o a better understanding of “EIT waves”. As a result\, we are starting t
 o move beyond a simple investigation of their physical nature\, instead 
 using them to study the corona through which they propagate. In this sem
 inar I will discuss the theories proposed to explain “EIT waves”\, placi
 ng them in the context of the observations available at the time and sho
 wing how they have been updated with improved observations and models. W
 e then look towards the future\, using a combination of ground and space
 -based instruments to examine how “EIT waves” may be used to study the s
 tructure of the solar corona and infer the properties of their associate
 d coronal mass ejections.
