The appearance of this year's Perseid meteor shower will reach its peak in Indonesia on August 13 in the morning.
Despite the best location to see this meteor shower is the countries in the northern hemisphere, parts of Indonesia, located on the equator can see several dozen meteors per hour.
"Do not be conceived as a spectacular meteor shower. Meteors rain this will look like a flash of light which leads to the constellation Perseus. There were about a dozen meteors per hour," said Chief Bosscha Observatory, Bandung Institute of Technology Lutfi Hakim sluggish when contacted from Jakarta, Wednesday (11 / Perseid meteor shower has been going on since July 17 and will run until August 24. Peak is expected to occur on August 13 at 06:30 to 9:00 pm.
Observation of meteor showers are best done after midnight until dawn. Since the peak of the meteor shower occurs in the morning, it would be difficult for the Indonesian people to watch.
From Indonesia, the position of the constellation Perseus in the northeast. In western Indonesia, this constellation rises at around 1:00.
As a result, just before dawn, his position is still too low, about 30 degrees from horizontal.
More eastern parts of Indonesia are lucky because the position of the constellation Perseus meteor shower is higher so it is more easily observed.
Researcher Bosscha Observatory, M Irfan, said the ideal conditions for observing the meteor is a bright sky and a location with a wide field of view in all directions.
Therefore, a good location is rural areas that are not much light and high areas.
"The observations can be done in the city, but the possibility of seeing meteornya will be very low," he said.
That need to be aware of is the possibility of another meteor sightings that are not included in the Perseid meteor shower. Meteors are included in the Perseid meteor shower leading from north to south.
As for which direction it is outside the ordinary meteors that appear every night.
The judge said, the stones are a source of a Perseid meteor shower comes from the comet 109P/Swift-Tuttle.
Every August, Earth entered a comet's trajectory so that the former dust and rock left in the path of comet entered the Earth's atmosphere as a meteor shower, with a speed of about 60 kilometers per second. This comet's closest position to the Sun which last occurred in 1992.
Although the Perseid meteor shower has been going on since the 1990s, until now the meteor shower will still occur. According to Hakim, it happens because of the large diameter core of the comet, which reaches 9.7 kilometers according to space.com.
Although there repeatedly, this meteor shower will not cause any significant effects for the Earth. In the long term, continued the judge, the number of meteor showers can cause buildup of dust in the upper atmosphere of Earth so that it can block the sun light.
They can also contaminate dust satellite motor that trigger damaging man-made satellite.
