Other Observations
A total solar eclipse forms a rare opportunity to observe the corona (the outer layer of the Sun's atmosphere). Normally this is not visible because the photosphere is much brighter than the corona. According to the point reached in the solar cycle, the corona may appear small and symmetric, or large and fuzzy. It is very hard to predict this prior to totality.
Phenomena associated with eclipses include shadow bands (also known as flying shadows), which are similar to shadows on the bottom of a swimming pool. They only occur just prior to and after totality, when a narrow solar crescent acts as an anisotropic light source.

Famous quotes containing the word observations:
“Science is a dynamic undertaking directed to lowering the degree of the empiricism involved in solving problems; or, if you prefer, science is a process of fabricating a web of interconnected concepts and conceptual schemes arising from experiments and observations and fruitful of further experiments and observations.”
—James Conant (1893–1978)
“Jerry: She’s one of those third-year girls that gripe my liver.
Milo: Third-year girls?
Jerry: Yeah, you know, American college kids. They come over here to take their third year and lap up a little culture. They give me a swift pain.
Milo: Why?
Jerry: They’re officious and dull. They’re always making profound observations they’ve overheard.”
—Alan Jay Lerner (1918–1986)
