August 21, 2017 we will experience an eclipse of the sun.
To see where it will be total and for how long this great app was developed.
Enjoy, but Don’t forget your eye protection. You must look for glasses that meet the ISO 12312-2 international standard for such products, NASA advises. To date, five manufacturers have certified their eclipse glasses meet that standard:
• American Paper Optics
• Rainbow Symphony
• Thousand Oaks Optical
• TSE 17
• Baader Planetarium (AstroSolar Silver/Gold film only)
You can buy the glasses online — the cardboard-frame versions cost just a few dollars.
Wear the glasses any time you want to look at the sun, even if there’s only a small sliver of the star peeking behind the moon in a partial eclipse.
