solar ecllipse on 22 july 2009

This solar eclipse will be one of those much waiting celestial phenomenon a total solar eclipse. It will be seen in India from 5.35 a.m. to 7.25 a.m. of July 22. and there will be a total eclipse for the duration of 6 minutes and 47 seconds.
The solar eclipse that will take place on Wednesday, July 22, 2009 will be a total eclipse of the Sun with a magnitude of 1.080 that will be visible from a narrow corridor through northern India, eastern Nepal, northern Bangladesh, Bhutan, the northern tip of Myanmar, central China and the Pacific Ocean, including the Ryukyu Islands, Marshall Islands and Kiribati.
A total solar eclipse occurs when the moon moves between the sun and the earth, blocking out the sun from the areas in the moon’s shadow. Without the sun’s light, the sky darkens enough for stars to be seen and the corona makes a spectacular halo around the moon.
According to a senior scientist, this solar eclipse will be counted as the third total solar eclipse to be visible in India in the past 15 years, a senior scientist said here. The next total solar eclipse will occur in 2087.
Bharat Adur, director, Akashganga Centre for Astronomy, and a former senior scientist with the Nehru Planetarium says, the sun would be covered up to 95 percent in Mumbai and 80 percent in New Delhi and other north Indian cities, and Bangalore, Chennai and other southern cities, It will be visible in most parts of India in varying degrees of totality, but it Bihar it will be nearly four minutes. In Iwo-Jima, near the Guam Islands in the Far East, its visibility will be as long as six minutes.
Expert Warnings:
It is very important to emphasise that viewing the eclipse with the naked eye would be very dangerous. Viewing the sun through a telescope or a binoculars without a proper filter is many times more dangerous - it could destroy your eyesight

NEW DELHI - As the world looks forwards to the century’s longest total solar eclipse Wednesday, there are superstitions galore in India. But science experts have urged people to do away with “false beliefs” and watch the celestial spectacle — as long as they do so the right way.
“There are several false beliefs prevalent in our society regarding solar eclipse. Some people even lock themselves up in their homes to avoid ‘the bad rays’ from the eclipse,” said Nehru Planetarium director N. Rathnashree.
Many also take a dip in holy rivers to cleanse themselves after the eclipse and some avoid cooking and eating during the eclipse. There are others who believe that pregnant women should refrain from sewing during the eclipse as it can lead to deformities in the foetus.
“I have been told that during an eclipse the number of germs increases. Therefore, no food is eaten or cooked during the event, and any food cooked before the eclipse is discarded,” said 32-year-old Janaki Singh, a marketing executive.
Rathnashree stressed that there is no cause for fear during an eclipse but people should take precautions while viewing the phenomenon.
“The total solar eclipse is a once in a lifetime opportunity and a very interesting activity. It should be watched under the supervision of experts with proper gadgets. I am flooded with calls and e-mails from people who want to know the impact of solar eclipse on them,” she said.
But in the past few years people have allayed their fears and do come out in large number to watch such celestial events.
We are organising several trips to totality locations for people to watch the eclipse. Believe me people are so excited that they are ready to travel several kilometres from here to have a better view of the eclipse, Chander Bhushan Devgun, president of the Science Popularisation Association of Communicators and Educators (SPACE), told IANS.
SPACE, a Delhi-based organisation working to make science and astronomy popular among youngsters, is taking people to Varanasi in Uttar Pradesh and Sasaram near Patna in Bihar.
The total eclipse, which starts at sunrise in Surat in Gujarat, is expected to last six minutes and 44 seconds, making it the longest till 2132.
The moon’s shadow will be so large during this eclipse that even at sunrise the duration of totality will be over three minutes. The shadow very quickly moves across the breadth of India towards Arunachal Pradesh. It spans a third of the entire path in India - 900 km out of 2,500 km.
“It is very important to emphasise that viewing the eclipse with the naked eye would be very dangerous. Viewing the sun through a telescope or a binoculars without a proper filter is many times more dangerous - it could destroy your eyesight,” Rathnashree warned.
According to her, the safest way of viewing a total solar eclipse is through the method of projection.
A pair of binoculars can be used along with a long hardboard box to obtain good projected views of the sun for safe solar viewing, she said.
“By projection method, a pinhole or small opening is used to cast the image of the sun on a screen placed a half-meter or more beyond the opening,” she added.
If you don’t have access to a telescope or binoculars, Rathnashree explained an easy method of using a kitchen sieve with small perforations.
Hold the sieve just above the ground, tilting its face towards the sun. Moving the sieve a little away from the ground, one can see an image of the sun forming, which will show the eclipse when it occurs.
The people should also avoid watching solar eclipse using sunglasses, smoked glass, colour film, black-and-white film that contains no silver, or photographic negatives with images on them.
Nehru Planetarium, in collaboration with the Amateur Astronomers Association, Delhi, will be conducting a public sky-watch for the eclipse at the planetarium.
Our experts will be available to guide people in watching the beautiful event, Rathnasree said.
