Total Solar Eclipse 2009, Varanasi and Sasaram

In a season when most Eclipse chase sites in India were washed out, the Bohemians had a blast with both sites at Varanasi and Sasaram getting to see totality. We consider ourself extremely fortunate to having witnessed natures most simple but spectacular event inspite of the threat of looming monsoons. My sympathies with all those who got clouded or rained out

Mark your calendars folks, its surya-grahana time in India again. Come July 2009 the moon will eclipse the sun as seen from India, Bhutan,Bangladesh,China, Japan and the Marshall Islands. Its going to be the longest solar eclipse for over a century and guess what, this time the path of totality passes through India. This eclipse pass over India comes after almost a decade. The last two eclipses happened in 1999 and 1995.

Totality

The eclipse begins on the 22nd of July 2009 at around 5:30 am IST in India and spends almost two hours passing the subcontinent. The path of totality will pass through central India passing over Surat, Ujjain, Baroda, Bhopal, Patna, Darjeeling, and Dibrugarh in the far east. Rest assured the Bohemians will be out there somewhere chasing the eclipse.!!!!

Eclipse Safety : Observing Eclipse Do”s and Don”ts

warning Before we go on I must warn you to NEVER EVER look at the sun especially the PARTIAL PHASE through unprotected eyes or homebrewn filtering mechanisms.

The use of homebrewn filters is recommended to seasoned astronomers only who understand the risks involved! There are however very simple ways to observe an eclipse without putting your eyes in harm”s way

One of the simplest method to observe the sun safely is through a pinhole projection camera. This can be used for viewing the partial phases of the eclipse. During totality however, it is perfectly safe to watch the eclipse naked eye.

Alternatively you may use a solar filter

The first thing you must remember is that the human eye has no nerve endings, so if you burn your retina, it will not hurt. 😛 , which is all the more reason that caution is advised while observing the sun

It is never safe to look at a partial or annular eclipse, or the partial phases of a total solar eclipse, without the proper equipment and techniques. Even when 99% of the Sun”s surface (the photosphere) is obscured during the partial phases of a solar eclipse. This is primarily because nearing totality the ambient light levels become so less that our pupils dilate and the iris tries to allow in more light into the eye.

During the partial phase any surge in sunlight, like the one seen during a diamond ring formation can cause excessive solar radiation entering the eye and causing a burn on the retina.


In spite of these precautions, the total phase of an eclipse can and should be viewed without any filters whatsoever. The naked eye view of totality is not only completely safe, it is truly breathtaking
