16. The Solar Corona What is it? How did it get that way?

17. Corona shines at level of one millionth the photosphere. It is Thompson scattered sunlight

18. To understand astronomical objects, astronomers take spectra The spectrum of the corona reveals its most interesting characteristic

19. The dominant ionization state depends on the temperature…example N
