Tips on How to Safely View the Great American Solar Eclipse

During childhood, you may have heard many dreadful things about a solar eclipse ranging from the myth of a giant snake swallowing the sun to viewing it with naked eyes may make you blind. Even though the new-age kids are not caught up with by these superstitions, some of the dangers of viewing solar eclipse are real, but not as overstated by the media or the discussion groups.So, here in this article, we will review some tips on how to safely view the Great American Solar Eclipse 2017 in its totality.


Stages of eclipse

Total solar eclipse occurs in five stages. It is only in one stage, which is so brief, the moon fully covers the brightest parts of the sun’s disk for a few minutes. In 2017 eclipse, it is expected to be in between one and a half minutes to two minutes forty five seconds at various places. During this time of totality, you can look at the sun with naked eye, but during the other phases of the eclipse, you shouldn’t observe the sun without a solar glass, filter or other preventive objects over your eyes or lenses of a telescope, camera, or binoculars. So, you can start viewing the solar eclipse 2017 with a filter and at the second phase, which called second contact, the trailing limb of the moon will cover the son and the last beads of light may go fainter as the moon fully covers the sun. You can see the sky and the surrounding landscapes completely darken, animals and birds go quiet, and the air gets cooled noticeably. It is when the totality starts and during when you can remove the filters to witness the awesome view of the red chromosphere and icy-white corona surrounding the fully dark moon.


Solar filters for observing solar eclipse

Solar filters for naked eye viewing are quite inexpensive and available in plenty. A simple pair of solar viewing cards or eclipse glasses costs only a few dollars and can provide excellent view of the sun’s disk without using a telescope. The simple plastic solar filters can help reduce the intensity of sun’s light by a factor of about 100,000 or more to be safer for human eyes.These filters pass only a little light, so you cannot see anything other than the bright disk of the sun through it. During the brief phase of totality of eclipse while the moon covers the sun fully, you may have to remove the filters to witness the action. After a couple of minutes, when the sun pokes out like a diamond ring, immediately look away and put the eclipse glass back on to continue viewing.

Pinhole projection

There is another simple and fully risk-free method for viewing the progress of solar eclipse is the use of a pinhole camera. It can be easily made with a piece of thick cardboard through which you have to poke a little hold and hold it up to the sun. You can see a fine projection of the sun’s image on the ground behind or against a wall. The farther you cast the image, the larger it will be. You can look at this image during the time of eclipse to see the exact replica of the live action there.
