Total Lunar Eclipse

15^th June Full Moon night is going to be a beautiful darkest night

with a unique Total Lunar Eclipse

 

On the night of 15th June 2011 more than half the world will have opportunity to watch one of the darkest Lunar eclipses.

This will be the darkest lunar eclipse in almost 100 years as the centres of the sun, the earth and the moon would nearly be on one straight line. The earlier darkest lunar eclipse was observed on August 6, 1971 and the next one would be 47 years from now on, on June 6, 2058.

People leaving in eastern Africa, the Middle East, central Asia and western Australia will have opportunity to observe the entire eclipse, from beginning to end. At mid-eclipse the Moon will be over head at Mauritius.

Total Lunar Eclipse (Chandra Grahan), on June 15, 2011 will be visible in India, Dubai, Qatar, Oman, Bahrain, Saudi Arabia, Nepal, Sri Lanka, Singapore, Malaysia and western parts of Australia. The Chandra Graham will be taking place in India between 11:53 pm on June 15 to 03:32 am early morning on June 16, 2011. Total Lunar Eclipse - the moon is fully covered - is from 00:52 hrs to 02:33 hrs. The eclipse’s total phase lasts for 100 minutes.

A lunar eclipse takes place when the moon enters the shadow of the earth. On 15^th June night, the earth is directly between the moon and the sun, blocking the sunlight reaching the moon. On this night the moon and the sun are in opposite side of the earth. One can experience a solar eclipse on the surface of the moon.

Other than the near perfect alignment of these solar system bodies, atmosphere plays its role too to make the eclipsed Moon really very dark. This eclipse of June 15th is likely to be one of the darkest one due to the ashes thrown in the Earth's atmosphere by the recent eruption of Iceland's most active volcano, Grimsvotn.

The moon will in the penumbral shadow of the earth at about 10:53 pm. Nothing much will be noticeable to the untrained eyes for next 30 to 40 minutes. After that one might notice gradual change in the brightness on the lunar disk. By 11:53 the moon will be in the umbra of the earth's shadow. The dark shadow will progress on the lunar disk. This will be quite noticeable to the naked eyes.

The total lunar eclipse to be visible on June 15, 2011 will be the first of two lunar eclipses in 2011 and the third of all eclipses that occur throughout the year. 

Gujarat Science City has organized a series of educational activities and outreach programmes for school and college students as well as the common public on this celestial event. A day-long workshop on understanding eclipse, live phone in programme on Gyan Vani, interactive sessions with eminent experts along with a lots of eclipse awareness games, puzzles have been organized on 15^th June 2011.

In the evening, elaborate arrangement is being made at the amphitheater in the Science City for safe viewing of the total lunar eclipse through telescopes and naked eye along with interaction with scientists. There will be special shows to screen the IMAX 3D movie “Walking on the Moon”.

Interested students, teachers and sky gazers are invited to participate in the workshop and to observe the total lunar eclipse at Science City.

Eclipse and Science

A total solar and lunar eclipse is probably the most spectacular astronomical event that most people will experience in their lives. There is a great deal of interest in watching eclipses, and thousands of astronomers (both amateur and professional) travel around the world to observe and photograph them. A total solar and lunar eclipse presents a fun, exciting and educational opportunity to teach young people about science.

1.     An eclipse offers students a unique opportunity to see a natural phenomenon that illustrates the basic principles of mathematics and science that are taught through elementary and secondary school. Indeed, many scientists (including astronomers!) have been inspired to study science as a result of seeing a total solar eclipse.

2.     Teachers can use eclipses to show how the laws of motion and the mathematics of orbital motion can predict the occurrence of eclipses.

3.     The use of pinhole cameras and telescopes or binoculars to observe an eclipse leads to an understanding of the optics of these devices.

4.     The rise and fall of environmental light levels during an eclipse illustrate the principles of radiometry and photometry, while biology classes can observe the associated behavior of plants and animals.

5.     It is also an opportunity for school children to contribute actively to scientific research - observations of contact timings at different locations along the eclipse path are useful in refining our knowledge of the orbital motions of the Moon and earth.

6. It is also an opportunity for children of school age to contribute actively to scientific research - observations of contact timings at different locations along the eclipse path are useful in refining our knowledge of the orbital motions of the Moon and earth, and sketches and photographs of the solar corona can be used to build a three-dimensional picture of the Sun's extended atmosphere during the eclipse.

For everybody, the eclipse is a unique opportunity to admire and celebrate the beauty and inspiration of the celestial experience. The experience of such a moment triggers questions on the cosmos, our Earth in space, and our human condition – a shared unforgettable experience that crosses boundaries of language, race, religion and culture.

Let’s not miss this spectacular event of this year. Let us bring the thrill of watching this grand event of the people, at the same time, helping them to develop a scientific outlook.
