IF the sky on a sunny Saturday night, the people of Indonesia will be treated to the natural phenomenon of a total lunar eclipse. Last phase of the eclipse events this year will occur on Saturday (12.10.2011) starting at 18:33 pm until 0:30 pm. The eclipse is quite special because the last total lunar eclipse in 2011.
Head of Bosscha Observatory, sit Judge Lutfi, said the peak total lunar eclipse, when the Earth's shadow covering the moon, will occur at 21:06 pm until 21:57 pm or for 51 minutes 8 seconds.
"The eclipse will be visible throughout Indonesia. But, the most obvious can be witnessed in western Indonesia. Month when it will begin to rise from the east towards the north. At an altitude of 22 degrees above the horizontal line," he said when met at the Observatory Bosscha, Friday ( 9 / 12).
This year, said the judge, there are two events a total lunar eclipse seen in Indonesia. The first total lunar eclipse occurs in June and takes place after midnight. This time, a total lunar eclipse will occur on Saturday night, before midnight.
Hence, people can watch it before bed or while enjoying the weekend out with family or relatives.
Like the other lunar eclipse, the moon will be in shadow dark red earth. The judge said some people saw a black shadow.
However, the actual color is dark red because there terbiaskan sunlight by the Earth's atmosphere and join the shadow coloring.
In this event, the moon does not traverse the center of the shadow of the earth so that the eclipse will pass faster when compared to the total lunar eclipse in June that lasted for 101 minutes.
Lunar eclipse occurs due to the moon, earth and sun are in one straight line in sequence. The position of the moon are not too many are on the line that actually aligned with the earth and the sun so that sometimes occurs partial or total eclipse of the moon.
As the phenomenon of meteor showers, comet sightings, and other astronomical phenomena, said the judge, a total lunar eclipse can only be seen by the naked eye or telescope if not the night sky covered in cloud.
However, people who are eager to see the eclipse but can not see it because the clouds covered the sky in the area, people can still see the natural phenomenon is through video streaming that can be accessed through the site in www.bosscha.itb.ac.id Bosscha. Working closely with Kemenkominfo, the judge said, Bosscha conduct eclipse observation in several regions in Indonesia such as Yogyakarta, Mataram, Pekanbaru, and Bandung.
Therefore, if the cloud covered the sky in Bandung, the public could witness an eclipse of the moon through the streaming video taken from other cities that could have a brighter sky through the site.
According to data compiled Bosscha Observatory, this year a total lunar eclipse occurred two and four partial solar eclipse. Two total lunar eclipse can be witnessed from the territory of Indonesia, but the four partial solar eclipse could not be seen from the territory of Indonesia.
Four solar eclipse, according to him, just visible in the northern hemisphere. Only in 2016, said the judge, a total solar eclipse will be seen in Indonesia.
Astronomers Ma'rufin Sudibyo in the posts on social networking, Sunday (4 / 12), as quoted kompas.com, said there are unique this time of the eclipse. When totality occurred, the moon will appear to be in front of the Milky Way. So, if seen, behind the bloody moon will appear a fine mist.
Milky Way galaxy where Earth is ruled. Ma'rufin say, the Milky Way also "monster" that has claimed other small galaxies and is one of the oldest galaxies in the universe.
Bloody month will also have some companion Saturday night. One of Jupiter, that since some time ago persistent visible and can be seen with the naked eye.
In addition, the star Sirius the brightest star after the Sun will also be visible. There is also a cluster of seven stars or Pleiades sisters. Galaxies of Small and Large Magellanic Cloud will also be visible.
All the celestial bodies visible during the eclipse promises an interesting scene on Saturday night. However, all can vanish out of sight if the sky cloudy and rainy. So, just pray it never happens.
