shows this layer.

For the Sun, there are three layers representing the eclipse phases: the normal
Sun, the moment just before totality where a final burst of light is seen, and total-
ity. The normal Sun is a blurred yellow circle with a white center. The Sun Burst
is a basic ellipse with a white center and a surrounding halo effect, rotated 45

and right after totality and is commonly called the diamond ring effect. Totality

lines added to represent solar flares that only appear during totality. The sun
layer is illustrated in Figure 2.4 and can be seen in color at http://jfxbook.com.

Figure 2.5 shows the Sun Burst layer. This is the layer that is shown in the dia-
mond ring effect immediately before and after totality.

Figure 2.6 shows the Totality layer.
Figure 2.7 shows the combined layers for the moment before totality, commonly
called the diamond ring effect. These include the layers DarkSky, Totality, Sun-
