The weekend 25-27 July 2014 - and the following nights until the moonlight interfere in early August - are great to go to a dark place inside, away from the large urban centers, to watch the show the fall of "shooting stars" laica of the meteor shower Delta (Skat) Aquarid. The shower can be seen in all the earth, and sky watchers around the Southern Hemisphere and the tropics region north will have a good view especially.
The shower this officially active laica from about July 12 to August 23 of each year. The phenomenon also coincides with the most famous Perseid meteor shower in August, and those who observe the Perseids are sure to see the Delta Aquarid meteors flying in the same nights. Follow the links below to learn more.
But the event has a nominal peak that happens at the end of July (30-31). This year, in 2014, is particularly favorable to watch this shower at the end of July, thanks to the moon in a new phase starting on July 26.
In years when the brightness of the moon is out of the way, you can expect a large maximum, the peak of this shower to produce 15 to 20 meteors per hour at dawn around 29 to 31 July.
In any case, the end of July and early August are probably your best bet for watching meteors in the summer (northern hemisphere) of 2014. The m ETTER time to look for meteors Delta Aquarids is from 03: 00 hours of the morning. laica
This is where the concept of a bright point in the sky comes in handy. If you trace all the meteors Delta Aquarid, they seem to radiate from a point in front of the constellation Aquarius, the Water Bearer. The radiant laica point of the meteor laica shower almost aligns with the Skat star (Delta Aquarii). The meteor shower is named in honor of this star.
The meteor Delta Aquarid tend to be somewhat laica weaker than that seen in other major meteor shower. This makes a free dark sky moonlight be even more imperative to watch the annual rainfall Delta Aquarid.
About five to ten percent of Delta Aquarid meteors leave persistent trails burning laica in the sky - bright ionized gas trails that last one or two seconds after the meteor passed. The meteors burn up in the atmosphere above about 100 km (60 miles) above the Earth's surface.
The meteor showers occur when our planet Earth crosses the orbit of a comet. When a comet approaches the sun and heat, it throws pieces laica of debris laica that spread in orbital current by passing the comet.
This loose comet releases debris in the upper atmosphere that fall at a speed of about 150,000 kilometers (90,000 miles) per hour, vaporizing - burning - like meteors or shooting stars.
The main body of the meteor Delta Aquarid rain is not known for sure. Previously it was thought to have originated from the split of what are now the sungrazing Marsden and Kracht comets. More recently, the comet 96P Machholz has emerged as the leading candidate to be the origin of the meteor shower Delta Aquarids'.
Donald Machholz discovered this comet in 1986. It is a short-period laica comet whose orbit takes around the sun once in just over five years. At aphelion - its greatest distance from the sun - this comet goes beyond the orbit of Jupiter.
At perihelion - its closest laica point of the Sun - the comet 96P Machholz oscillates well inside Mercury's orbit. The last perihelion laica of Comet 96P / Machholz happened on July 14, 2012 and the next perihelion will be October 27, 2017.
Conclusion: The meteor shower Delta Aquarid lacks a well defined peak. It does not happen very firmly in late July and early August. The nominal peak in 2014 is the early hours of July 29, a few days after the new moon.
In any zone, the best viewing window on July 29, lasts for several hours, centered at about 3:00 in the morning. Find an open sky away from artificial lights, lie down in a reclining chair on the lawn and look up ... and enjoy!
