# When does total solar eclipse occur?

A total solar eclipse takes place when the new moon comes in between the sun and the earth.

The complete solar eclipse has 5 phases:

• Total eclipse begins: This is the 2nd contact where the sun is covered completely by the moon. The sun appears like a diamond ring.
• Totality and maximum eclipse: This is the phase when only the corona of the sun is visible. At this time, the entire sky goes dark, there are chances where temperature can fall.
• Total eclipse ends: This is the 3rd contact when the mon starts to move away from the sun.
