when the moon passes in a direct line between the Earth and the sun, it is called a "solar eclipse". The moon has to be at an exact correct phase during an eclipse. There also has to be a new moon.
There are between 2 and 5 solar eclipses every year, each one visible only in a limited area. The New Moon and Sun have to be near a lunar node. It happens a little less than 6 months apart and lasts about 25 days.
