Two local science organizations are offering help to people wondering how to observe the solar eclipse, which will impact all of the mainland United States on August 21. Special eclipse shades will be available. Mining the data from NASA, here are all the total solar eclipses touching the USA over the next 100 years. Within the path of totality, you can safely witness the two or more minutes when the moon completely covers the sun with the naked eye. The eclipse is expected to have 81 percent coverage from this location.
As a measure of excitement surrounding the event, a leading supplier of solar lenses, Arizona-based Thousand Oaks Optical, has sold enough of its filters this year alone to produce roughly 100 million pairs of glasses, company owner Pat Steele-Gaishin told Reuters. Safety glasses for viewing will be on hand for free while supplies last. The American Astronomical Society, a NASA partner, has verified that these manufacturers are making eclipse glasses and handheld solar viewers that meet the ISO 12312-2 global standard for such products.
The legitimate glasses, which offer no views outside the eclipse, carry their own hazards, however.
Don't look at the sun during the eclipse or at any other time through an unfiltered camera, telescope, binoculars or other optical device, even if wearing eclipse glasses or a solar viewer.
