Safety Tips
Are Eclipse Glasses or Handheld Solar Viewers
actually legit and safe to use?
https://eclipse.aas.org/eye-safety/iso-certification
Advice is to test all purchased eclipse viewing glasses [as there are counterfeit ones with the valid ISO #] prior to the eclipse by heading outside tonight
as the sky starts to get dark (similar to what will happen tomorrow 8/21).
Look up at an outside bright light / street lamp.
You should NOT be able to see it at all.
Regular cameras need a special filter - and staring at the sun via a camera lens can also damage your eye's retina. It is never safe to look directly at the sun through a telescope, binoculars, or camera lens without a solar filter.

Northern NJ will not experience a view of the totality of the eclipse,
when the brightness of the sun is totally obscured by the moon!

A homemade pinhole projector is the safest way of watching the eclipse;
you can make one yourself with 2 thin pieces of stiff paper or cardboard,
or paper plates.
Here’s how:
Put one piece of paper or cardboard (or a paper plate) on the ground.
Poke a tiny, round hole into the other piece of stiff paper or cardboard.
With your back to the sun, raise the cardboard with the hole in it above your head and aim the light coming through the hole at the paper or
cardboard on the ground.
The hole will project an image of the eclipse on to the other paper.
