Planets
Mercury , having just passed superior conjunction, reappears in the lights of the sunset in the west and south-west, just after the 10th of the month. On March 9 is in conjunction with Uranus while March 15 Jupiter, the latter junction is easily visible, since the planet has left more than 16 degrees from the Sun The March 23 is the greatest eastern elongation , visible to the west just above Jupiter. Then he quickly began to draw closer to the Sun
Venus is always visible to the southeast at dawn. However, day after day, anticipating less the sunrise, the almost two hours in early March just one hour later this month. This is partly because the planet is approaching at an angle to the sun, but mostly because the ecliptic is "stretched" more and more to the east.
Mars is undetectable for the entire month because of the close proximity with the Sun angle
Visibility evening Jupiter va terminando . Ancora ben visibile nella prima decade del mese dopo il tramonto del Sole per almeno un’ora, a fine mese scompare tra le ombre del crepuscolo. Lo ritroveremo a fine estate.
Saturno si sta preparando all’imminente opposizione (4 aprile) ed è il protagonista della notte, sorgendo già prima delle 21. Facilmente rintracciabile nella costellazione della Vergine, dove supera in luminosità la stella più brillante della costellazione, Spica.
Urano è inosservabile per tutto il mese a causa della notevole vicinanza angolare con il Sole. Il 21 marzo is in conjunction with the Sun
Neptune is undetectable for the entire month because of the close proximity with the Sun angle
Other phenomena
March 1: Moon-Venus conjunction: A thin crescent moon descending (stage 12%) finds himself less than 2 ° east of Venus shines at magnitude -4.1. objects rather low on the horizon and observation difficult.
March 6 : Moon-Jupiter conjunction. A thin crescent moon rising (phase 3%) and the giant of the Solar System approach a little less than 7 degrees to the west-southwest. It is advisable to observe the configuration when the sky gets dark, because the two objects fade away a little after 21.
March 20: Moon-Saturn conjunction, to the southeast late in the evening. A nearly full moon (waning phase of 98%) approaches the ringed giant of the Solar System. Beautiful the triangle completed by the bright Spica, since the configuration is projected in the middle of the constellation Virgo
March 21: the conjunction of the previous evening evolves into a beautiful "slipped" Moon, Spica and Saturn by bottom to top. The three items heaven is practically 10 degrees (the width of a clenched fist holding the outstretched arm) of each other, always to the southeast at midnight.
March 21: Spring Equinox. In all the places on Earth the day and night last exactly 12 hours, the terminator passing through the two poles of Earth. For the accuracy of the equinox occurs at 23e21 March 20 (Universal Time), for us that we are more than an hour east of the prime meridian (Greenwich) the event is to slip at 00e21 21 March.
March 27: Venus-Neptune conjunction, east-southeast at dawn. The brightest of the planets (magnitude -4) finds himself just 13 minutes from the most distant planet in the Solar System. The observation is not very simple because the objects are still quite low when the sky begins to lighten, but providing free of horizons can be put in the same shot the two planets so far away.
March 27 : enter into daylight saving time. At 02e00 clocks are put forward one hour. Daylight savings time will remain in force until 30 October.
