Many Astronomical Events Coming Up!

Tuesday, September 14th, 2010

September is a busy month: besides Jupiter and Uranus reaching opposition at the same time, Mercury will reach its greatest western elongation, and the Autumnal Equinox and harvest moon will occur.

Mercury will reach its greatest western elongation on September 19. It will rise over an hour before sunrise and should be a great telescope target in the eastern sky into late September. It will appear at its highest and brightest point on the 19th.

The Autumnal Equinox occurs September 22 and the harvest moon follows September 23. The harvest moon is the full moon that occurs closest to the autumnal equinox, called that because its rising time nearly overlaps the setting sun so farmers could continue the harvest into the night hours due to the moon’s light. Since the Autumnal Equinox, when the sun rises due east and sets due west (everywhere except at the poles), is on September 22, the full moon the following night (September 23) is the harvest moon.

Double Opposition of Jupiter and Uranus, September 21, 2010

Friday, September 10th, 2010

On September 21, Jupiter and Uranus will both reach opposition, when they are closest to Earth and opposite the sun. Outer planets are best seen when at opposition, but these two together will be an amazing event.

They will be up in Pisces all night, rising as the sun sets and setting as the sun rises. The bright Jupiter will be easily visible to the naked eye, though an especially interesting view can be seen right now with binoculars or a telescope: Jupiter has currently lost its south equatorial band, making the Great Red Spot stand out very clearly. This has happened 15 times since 1919, but doesn’t occur regularly, and could ‘fix’ itself at any time, though it could just as easily take a couple of years.

At the same time, Uranus reaches its opposition, just about a degree away from Jupiter. Because of the nearly-full harvest moon around the same time, spotting Uranus with the naked eye will be nearly impossible, but it should be easily seen with binoculars.This event is an auspicious astrological event, supposedly preceding a major scientific breathrough or other drastic global change, but even if you don’t follow astrology, this will be an amazing event that you don’t want to miss. This Jupiter-Uranus double opposition won’t occur again until 2037, 27 years from now.

Jupiter and Uranus
Jupiter is in proximity to the planet Uranus all month and is a great starting point for location Uranus. By September 18th, Jupiter and Uranus are less than 0°50’ from each other and they both reach opposition on the same date, September 21st!

Autumnal Equinox

Autumn begins on September 22nd when the Autumnal Equinox occurs. The Autumnal Equinox occurs when the tilt of the Earth is in tangent with the orbit of Earth around the Sun.  This point marks the beginning of Autumn.  An Equinox has an equal amount of daylight and nighttime.

Lunar Events

The Full Moon for September occurs on the 4th.  The Full Moon is called the Full Fruit Moon and is also known as the Barley Moon.

The New Moon for September occurs on Friday, September 18th this will make the weekend of September 19-20 as the best weekend for deep sky observing.

Mercury

Mercury crosses from evening to morning hours this month.  Mercury is observable in the evening until around September 14th when it disappears into the glare of the Sun.  Mercury re-emerges into the evening around September 26th.  Mercury is in retrograde motion between September 7th through September 28th.

The above movie shows the path of Mercury during the month of September. Each frame is one sideal day. Note the retrograde motion as is moves past the Sun as it crosses from evening to morning hours.

Mercury begins September in the constellation Virgo (The Maiden) and on September 22nd it crosses into the constellation Leo (The Lion) where it spend the rest of the month.

Venus

Venus is the Morning Star for September. Venus begins September in the constellation Cancer (The Crab) until September 10th went it moves into the constellation Leo (The Lion).
