This is the beginning of the eclipse, as the moon begins to cover the upper right corner of the sun, at 11:40 A.M. | |
At 12:10 P.M., the sun is 90% eclipsed. | |
Just seconds before the start of the totality phase of the eclipse at 12:18:49 P.M., the phenomenon known as the "diamond ring" effect can be seen. It is caused by the tiniest part of the sun that is still exposed (the "stone") combining with the beginning visibility of the corona around the sun. | |
During the 2 minutes of totality, the sun is completely blocked by the moon, and the chromosphere (ring of hot gases) around the sun is visible. |
