It is a syzygy.
Of course, you can always draw a straight line from Moon to Sun, so really, to be interesting, the alignment would involve Earth, Sun, and the Moon. If they are in a straight line, there will sometimes be solar eclipses, or lunar eclipses.

Spring tides are caused by the combined gravitational pull of the sun and the moon when they are aligned. However, solar eclipses occur when the moon passes between the sun and the Earth, blocking the sun's light. This alignment for a solar eclipse does not coincide with the alignment necessary for spring tides.
The Moon.
How can astronomers predict planetary alignment
It happens when the sun and the Moon are in alignment.
were maya astronomers were able to predict eclipse of the moon
Uh... yeah
There are lunar eclipses, in which the Moon goes into the Earth's shadow, and solar eclipses, in which the Earth goes into the Moon's shadow. Depending on how precise is the alignment of the Sun, Earth and Moon, the eclipse may be total, or if the alignment isn't perfect, a partial or penumbral eclipse can occur.
There are normally two solar eclipses each year. However, due to a curious alignment of the Earth, Moon and Sun, there will not be ANY solar eclipses in 2011!
Mainly astronomers. But cosmologists and astrophysicists will also be interested in outer space.
my late night booty call.....
As total solar eclipses are very rare and spectacular, the sight of them is much sought after.
