I will explain how we observe the Sun’s atmosphere, especially stressing spectroscopy, and describe the atmosphere’s structure and some of the ideas that explain how it is heated and maintained. The presentation will be based mainly on the programs I have worked on. I will start with what an O III filter does (and explain what O III means) and then expand the ideas of visual observing to what we learn by observing the ultraviolet (UV), extreme ultraviolet (EUV), and X-ray wavelengths. For flares I will describe some of my EUV spectroscopy work and what I’m trying to learn from it.
