This Month -Soon comes the spring and night observations are becoming more enjoyable. The March of significant astronomical interest: flickering stars and constellations in the sky, three meteor shower, a conjunction of planets and an occultation. On March 21 we will celebrate the Spring Equinox, the day the sun passes from the southern to northern hemisphere marking the start of spring (for the northern hemisphere and the beginning of autumn in the south). The March this year holds for us as a surprise: the closest full moon of the year. But should above all be characterized months after the planet Mercury, the planet while offering a unique sight to observers on earth coupled with Jupiter, somewhere very near, the space mission MESSENGER enters into orbit around Mercury in a historic moment for the exploration of distant worlds.

Stars and Constellations - In March you can see the constellation of Orion in the south and following the stars of the area to the right to get in the constellation Taurus the stellar cluster in the form V Yadon the head and portokalokkokino Aldemparan star in the eye of the bull. Going to the peak we find the constellation of the Charioteer. Bottom left of Orion Sirius will shine in the Big dog and left the Prokyonas in Canis Minor. To the east rises the constellation of Leo, with Saturn near Leo's brightest star Regulus. In this direction we find the dim Cancer with open star cluster known as the blister. Later at night it erupted and the Virgin in the south-east of the brightest star of the ear. A star worthy of attention this month is the famous Algol. variable star brightness is booming and remains visible all night. In fact there are two stars: the Algol A is 100 times brighter than our Sun and Algol B, a very faint star that orbits a with a period less than 3 days. When the procession was the B pass in front of the A overshadows much of the light as to the earthly observer so that the Algol system vary periodically in brightness so he took the title of the variable star.

Meteor shower - In March we have three main rains meteoroeidon:
On March 16 peak of the meteor shower effect on radiant point in the constellation Southern Crown (Stephanie). Normally you can see 5-7 hours of shooting, but this year the peak will occur near the full moon which will be difficult to observe the (much fainter) meteroeidon. On March 22 the meteor shower reaches its peak with an apparent radiant point in the constellation of the Giraffe (a northern constellation, just 22nd in the north celestial pole). Few expected shooting time, which is indeed very slow (speed is only 7 km. Per second). At around the same date peaks and rain Didymidon of March, which was discovered only in 1973 and some argue that, together with Kamilopardalides come from two clouds of dust left behind by the same cosmic object. If and when discovered were observed up to 50 metoroeidi time, the presence of the moon this year might prevent the observation of this meteor shower.

Planets - Symbolically, this month the smallest planet Mercury and the largest planet Jupiter will be in conjugation, a unique spectacle not to be missed. On March 7, the crescent will be close to the two planets, which will continue to approach each other in the coming days until March 15, when the apparent distance will be reduced to second, creating a better opportunity next year to see the two planets together. Another planet, the distant sky, will be among them but they are prohibitively dim to see it without the help of the telescope. Jupiter sets will progressively closer and closer to the sunset to go out in the morning sky. While it remains visible if you have a small telescope you can see the Southern Equatorial zone which reappeared and the famous Great Red Spot of the planet regained its color. On March 23, Mercury will be at maximum angular removed from the Sun and therefore higher in the sky at night suitable for observation, but then the brilliance will be reduced significantly compared with that of March 15. Saturn rises in the early evening and is in excellent position for observing around midnight when it culminates. The rings of Saturn offer excellent sight even with a small telescope, and are so inclined you'll be able to clearly see the Cassini buffer zone between the rings A and B. With a small telescope will also be visible to the largest storm ever recorded in the Saturn, which has been raging since last December. Apart from the planet itself will be seen the largest moon of Titan (astronomical size 8) and even potassium. If you have a telescope and also look for the fainter satellites of Dione, Rhea and Tethys (astronomy size 10) but the night should be dark (the first two nights of the month is perhaps more appropriate).

Moon - New Moon on 4 March, First Quarter on 12, 19 and Full Moon Last Quarter on 26 March. The Moon at apogee (406,583 km) on 6 March and at perigee (356,575 km) on 19 March. Since the Moon will be in the closest distance to Earth (perigee) and both will be full moon, tides are expected enhanced in many parts of the world. On 10 and March 11 the moon will be near the Pleiades star clusters and Yadon and the famous star Aldemparan. On March 13 the rim of the moon will hide the star Eta Geminorum Gemini. The occultation will last one hour and the phenomenon can occur even with a pair of binoculars.
