How to watch safely

Never look at the Sun without certified solar viewing glasses that meet the ISO 12312-2 standard. Sunglasses, smoked glass and exposed film are not safe. Check the glasses for scratches or holes before you use them, and supervise children.

Never point binoculars, a telescope or a camera at the Sun unless a certified solar filter covers the front of the optics. Don’t use eclipse glasses to look through unfiltered optics: the concentrated sunlight will burn through them and into your eye.

A pinhole projector is a safe, simple alternative: let sunlight through a small hole in card onto a surface behind it and watch the projected crescent. Only during totality, when the Sun is completely covered, is it safe to look without protection. Put your glasses back on the moment the first bright point of sunlight returns.

Questions

Can I use sunglasses?
No. Sunglasses let through far too much light. Use eclipse glasses that meet ISO 12312-2, or project the Sun with a pinhole.
Can I photograph the eclipse with my phone?
Only with a certified solar filter over the lens for the partial phases. Never look at the Sun through a camera’s optical viewfinder without a proper filter.
What is the difference between total, annular and partial?
In a total eclipse the Moon covers the Sun completely. In an annular eclipse the Moon is too far from Earth to cover it, leaving a bright ring. Everywhere outside those narrow paths sees a partial eclipse.
