Digital Typhoon: Annular Solar Eclipse on August 22, 1998
1. Annular Eclipse on August 22, 1998
When you observe the solar eclipse from the earth, it looks like a big black shade that covers the sun, but when you change the viewpoint to a satellite and observe the solar eclipse, it looks like a big black shadow casted on the earth. This is because the place that the solar eclipse can be observed looks darker than the surrounding area because of the decrease of the amount of light from the sun. Let's enjoy an astronomic scale phenomenon of the big black shadow of the moon moving through the day-night transition of the earth by the sun.
