Bangaloreans can experience 85% of the longest solar eclipse

On January 15, Bangaloreans (People in Bangalore) can experience 85% of the longest solar eclipse in 1,000 years.The eclipse will begin at 11 am and end at 3.15 pm, with the peak being around 1 pm.The next annular solar eclipse will take place only after 25 years.

Looking directly with bare eyes at the photosphere of the Sun (the bright disk of the Sun itself), even for just a few seconds, can cause permanent damage to the retina of the eye. Partial eclipses, annular eclipses, and the partial phases of total eclipses are never safe to watch without taking special precautions.The Sun can be viewed directly only when using filters specifically designed for this purpose. Such filters usually have a thin layer of aluminum, chromium or silver deposited on their surfaces that attenuates ultraviolet, visible, and infrared energy. One of the most widely available filters for safe solar viewing is a number 14 welder’s glass, available through welding supply outlets.

Sujata Virdhe, a former ISRO scientist, has developed special goggles to witness the eclipse safely. The goggles developed by Sujata have been measured at IIT, Madras, and Filmetrix, California, and cost Rs 25. They will be available at the planetarium, Visvesvaraya Museum, Sapna Book House, Gangarams, Higginbothams and other book stores.

Do not attempt to observe the partial or annular phases of any eclipse with the naked eye. Failure to use appropriate filtration may result in permanent eye damage or blindness!
