Moon Phases – September 2010

Here are the Moon phases in the Northern hemisphere for September 2010 and other interesting things of note in the sky.

1st September: Last Quarter
8th September: New Moon
15th September: First Quarter
23rd September: Full Moon

This month the planet Jupiter is in opposition.

Planets are said to be in opposition when they are opposite the Sun relative to the Earth. Jupiter will be in opposition on the evening of September 21st. If the sky is clear of cloud this will provide an excellent opportunity to see Jupiter as it rises as the Sun sets and sets as the Sun rises. Also, being at its closest to Earth it will appear at its brightest.

Using binoculars, you’ll perhaps get lucky and glimpse Jupiter’s four main moons – Io, Europa, Ganymede, and Callisto – as first discovered by Italian astronomer Galileo Galilei in 1609.
