Weather 101: Solar eclipses: "total" and "annular"

Posted: Updated:

**There will be an "annular" solar eclipse visible from Arizona on May 20, 2012.**

 

Solar eclipses are amazing to observe. To observe them, never look directly at them.  Instead, create a solar eclipse observing tool.

There are two types of solar eclipses: Annular and Total.

An annular eclipse doesn't mean we will observe one every year from our vantage point. Instead, when the moon gets between the earth and sun, it blocks MOST but not all of the sun's disc in our sky. The next two images illustrate an annular solar eclipse.

The following image shows a total solar eclipse.  Notice that there is a glow of the sun around the moon, but the disc of the sun is fully covered by the moon in a total solar eclipse.
