A total lunar eclipse,the second in 2011 (the last one was in mid-June) will take place on Saturday. Those who want to catch it can do so on the Inter-University Centre for Astronomy and Astrophysics (IUCAA) website,which will webcast the celestial event,when the sun,earth and the moon align themselves and the earths shadow totally eclipses the moon.
The next total lunar eclipse,experts say,isnt due until October 2014. A partial lunar eclipse will take place in June and a penumbral lunar eclipse in November next year
At 5:00 pm Indian Standard Time (IST),the moon will enter the penumbral shadow of the Earth and gradually be covered by the umbra. The sun will be above the horizon whereas in Kolkata sunset would be 10 minutes after moonrise.
Arvind Paranjpye,in charge of the Public outreach Programme,said,Once it the moon comes entirely in the shadow of the earth,the moon will turn crimson due to red components of sunlight. The eclipse can be seen from anywhere. However we will also be webcasting the eclipse so that people can log on to our website and observe the eclipse. This is a big moment for astronomy enthusiasts as this is the last total eclipse of the year,and after this there is no total eclipse a couple of years.
