Guidelines for monitoring the star rain for 2012

Guidelines for monitoring the star rain for 2012 Facts

The most important meteor shower in 2012 will be the Lyrids, due in April. Lyrids night promises to be a moonless, dark, so it will not hurt to enjoy the starry rain this year!

> April 22-2012, Lyrids

Lyrids meteor shower — April "shooting stars" — promises to be bright, with visible tails of meteors. During the peak of the event in the sky will fly 10-20 meteors per hour, a possible wave of hundreds of objects. Radiant of this shower is the constellation Lyra, rising in the north east around 10 pm. Fortunately, in 2012, the evening of 21 April in the sky new moon, so the sky is dark, and the Lyrids are visible, growing stronger day before dawn on April 22 or the next night (22/23 April).

> 5 and 6 May 2012, the Aquarids

This stream has a fairly broad maximum, but the greatest number of stars will be observed at the beginning of May (May 5-6, at dawn). Unfortunately, the event coincides with the full moon, this year, is located nearest to the Earth and affect the visibility of rain. In northern latitudes, the number of meteors will be low in the southern U.S. to 10-20 meteors per hour. In the southern hemisphere, the density is much higher (2-3 times). This radiant Aquarids will be in the east-south-east, about 4 in the morning. The meteors will fly above the Earth in a few days before the date specified in the forecast (broad peak of rain), but because of the bright moon, we can see only the big 5-6 May before sunrise.

> July 28-29, 2012, Delta Aquarids

This star rain will be seen in the Southern Hemisphere and in tropical north, between moonset and sunrise in the southern sky. In the temperate latitudes of the northern hemisphere meteor rate will be 15-20 per hour in dark sky. Unlike other meteor showers, the Delta Aquarids no pronounced peak, but they have more visibility period (late July — early August) due to high speed.

> 12-13 August 2012, the Perseid

Perseids will be visible after midnight towards the morning. Waning Moon almost hurt to see the flight of meteors, perhaps only a slight reduction in visibility during peak rain. Radiant and bright Perseid fast starts in the constellation Perseus, after which the flow is distributed across the starry sky. Many consider this the best star rain, as an hour in the sky at the same time can fly up to 50 brightest meteors with long tails. Rain is expected in the night of 11 to 12 or from 12 to 13 August.

> October 7, 2012, Draconids

Draconid radiant constellation Draco will be in the northern sky. This phenomenon is unusual for many reasons: the radiant is at an extremely high point in the sky, rain is better visible in the evening, not the morning. Usually Draconids — quiet rain with little leisurely meteors visible in an hour. In rare cases, this time can be seen hundreds of times more meteors than during other rains. When moonless weather phenomenon can be observed in the evening on 7 and 8 October.

> October 21, 2012, Orionids

On entering Waning Crescent Moon on October 20 between midnight and sunrise will be best to consider the star rain Orionids. The maximum number of meteors per hour at 15 rapidly rotating units. Sometimes they leave visible tails and bright light. Orionid radiant is north of Betelgeuse, the main star of Orion. Most of the meteors fly after midnight, the brightest objects appear closer to sunrise.

> 4-5 November 2012, Southern Taurids

Southern Taurids — the best gift for the passionate fans of star rains. It is very wide and long stream of meteors (visible from September 25 to November 25), but in an hour you can watch just about seven objects. Southern Taurid peak in 2012, around the time before dawn on November 5. Spectacle not hurt already stranded at this time waning moon.

> 11-12 November 2012, the Northern Taurids

Feed will be held from October 12 to December 2, with a modest number of meteors per hour (seven). Maximum of meteors can be seen near the morning on November 12 in the constellation Taurus. The moon will rise just closer to the rising of the sun and will not prevent viewing albeit slow moving, but quite bright Northern Taurids.

> 16-17 November 2012 Leonids

Famous Leonid radiant is in the constellation Leo. History remembers the Leonids of 1966, when the sky could be seen thousands of meteors per hour, creating the effect of the rain. All objects are moved from one point (the constellation Leo) and create the desire to bend down to the ground — it was so impressive sight. Leonids 1966 was no exception, as it does not fit into the normal cycle of movement of meteors (33-34 years) with the number of 10-15 meteors per hour. Best star rain will be visible just before dawn on November 17. The moon sits in the early evening on November 16, and the sky is dark enough.

> December 13-14, 2012, the Geminids

At the end of the year traditionally the star parade rains Geminids (50 per hour). Together with the Perseids this rain is the most spectacular. December 13-14, New Moon is expected at the peak of the Geminids, which will create the best conditions for observation, which can start as early as 9.10 pm, is expected to peak around 2 am.

To see the star rain, it is important:

— dark sky, Moon (during Lyrids, Northern Taurid and Geminid);

— know the date and time of the event, spinning round the sun, the earth intersects with streams of meteors, comets icy particles. When this cometary debris enters our atmosphere, it evaporates, and we see a trace of it in the form of evaporation "star Rain."

— choose a convenient place of observation, have binoculars;

— remember that all forecasts are approximate, despite considerable efforts of astronomers
