Viewing Eclipse of the Sun Safely

Watching a solar eclipse will be a breath taking experience especially because of it’s rarity and mystery. However, it comes with a warning! Our sun emits dangerous radiations. Never look directly at the Sun without proper solar filter even when if the Sun is almost completely blocked during the solar eclipse or by the clouds.

Don’t stare at the sun without protective glasses. Avoid using improper solar filters such CD, plastic bag, sunglasses, exposed x-ray film etc. to view the sun as harmful radiation can still pass through these objects.  You can purchase a solar eclipse glass. Solar UV radiation can burn the retinas at the back of your eyes, and cause permanent damage or even blindness. Another safe method of viewing the sun is to use a projection of the sun using small pin-hole camera or binocular or a small telescope.

Upcoming activities and observation for this eclipse will be updated on this page soon.
