Here we can inform each other of the situation of the masses in night sky and important astronomical events in future and discuss about their conditions

March 29: Sirius and M41 in the same field of view
This is a good week to look for Sirius in the evening sky. The night sky’s brightest star (at magnitude –1.5) appears in the southwest after twilight ends
If you point binoculars at Sirius, look for the pretty star cluster M41 in the same field of view, just 4° below the star

March 31: asteroid 6 Hebe near Mars
Tonight offers a good opportunity to track down the asteroid 6 Hebe through your telescope. The 10th-magnitude space rock lies approximately 7° north of Mars, but it is easier to find by one of Leo’s stars.
Hebe stands 2° east of the fine double star Gamma (γ) Leonis, which shines at 2nd magnitude

April 5: Asteroid 6 Hebe near Leo
Tonight offers a good opportunity to track down the asteroid 6 Hebe through your telescope. The 10th-magnitude space rock lies approximately 7° north of Mars, but it is easier to find by scanning just over 1° east of the fine double star Gamma (γ) Leonis, which shines at 2nd magnitude

April 6 -Full Moon. The Moon will be directly opposite the Earth from the Sun and will be fully illuminated as seen from Earth.
April 15 - Saturn at Opposition. The ringed planet will be at its closest approach to Earth and its face will be fully illuminated by the Sun. This is the best time to view and photograph Saturn and its moons.
April 21 -New Moon. The Moon will be directly between the Earth and the Sun and will not be visible from Earth. This phase occurs at 07:18 UTC.
April 21, 22 - Lyrids Meteor Shower. The Lyrids are an average shower, usually producing about 20 meteors per hour at their peak. These meteors can produce bright dust trails that last for several seconds. The shower usually peaks on April 21 & 22, although some meteors can be visible from April 16 - 25. With no moon to get in the way this year, this really should be a good show. Look for meteors radiating from the constellation of Lyra after midnight.
April 28 - Astronomy Day Part 1. Astronomy Day is an annual event intended to provide a means of interaction between the general public and various astronomy enthusiasts, groups and professionals. The theme of Astronomy Day is "Bringing Astronomy to the People" and on this day astronomy and stargazing clubs and other organizations around the world will plan special events. You can find out about special local events by contacting your local astronomy club or planetarium. You can also find more about Astronomy Day by checking the Web site for the Astronomical League.

April 15 - Saturn at Opposition
Saturn lies opposite the Sun in our sky tonight and reaches its peak visibility for 2012. The ringed planet appears low in the east as darkness falls and it climbs higher in the southeast
Saturn lies among the background stars of Virgo, just 5° from Spica. The planet shines at magnitude 0.2, noticeably brighter than Spica

April 16: Winter Hexagon
Although the calendar may say it is spring, the so-called Winter Hexagon remains prominent on April evenings. One of the sky’s largest asterisms — a recognizable pattern of stars separate from a constellation’s form — the hexagon stands out in the western sky after darkness falls.
To trace this asterism, start with southern Orion’s luminary, Rigel. The second stop is brilliant Sirius in Canis Major. Next, pick up Procyon in the faint constellation Canis Minor, then the twins Castor and Pollux in Gemini, followed by Capella in Auriga, Aldebaran in Taurus, and finally back to Rigel.

Sunday, April 22: Crescent Moon is near jupiter
Look to the western sky after sunset, and you’ll see a slender crescent Moon hanging just a few degrees under Jupiter. The pretty conjunction appears even more spectacular against the colorful background of twilight. Unfortunately jupiter will disappear in the Sun’s glare by the end of the month and won’t return to view until it climbs into the morning sky in June.
The Moon reaches apogee, the farthest point in its orbit around Earth. It then lies 406,419 kilometers from Earth’s center.

Wednesday, April 25: The position of Saturn in Virgo
Although Saturn reached its peak April 15, when it appeared opposite the Sun in our sky, our view of the ringed planet hardly diminishes this week. It remains on display all night among the background stars of Virgo, hanging in the southeastern sky as darkness falls and climbing high in the south by midnight local daylight time.
Saturn continues to shine brightly, too, at magnitude 0.3. It appears noticeably brighter than Virgo’s brightest star, Spica, which lies 5° southwest of the planet.
