How to See the Eclipse: Create a Pinhole Viewer, Watch On-line, etc

Since the first total Eclipse that traverses the U.S. from west to east happens today (and it's the first time in 99 years), here are some resources to help you experience it.
This graphic shows the BEST TIMES to experience the eclipse across the USA
The eclipse enters the United States at 10:15 a.m. PDT off the coast of Oregon and exits the U.S. at approximately 2:50 p.m. EDT in South Carolina.

RULES: Never look directly at the Sun without proper eye protection. You can seriously hurt your eyes and even go blind.

Projecting the Sun through a box projector, or using binoculars or telescope, or simply 2 pieces of card is a safe and easy way to view a solar eclipse.

DIY: Simple Card Projector:  The simplest and quickest way to safely project the Sun is with a projector made from only 2 pieces of card or paper.

You Need:  2 pieces of stiff white cardboard, e.g. 2 paper plates; alternatively, 2 sheets of plain white paper;  a thumbtack, a sharp pin, or a needle

What to Do:

  1. To make a quick version of the pinhole projector, take a sheet of paper and make a tiny hole in the middle of it using a pin or a thumbtack. Make sure that the hole is round and smooth.
  2. With your back towards the Sun, hold 1 piece of paper above your shoulder allowing the Sun to shine on the paper.
  3. The 2nd sheet of paper will act as a screen. Hold it at a distance, and you will see an inverted image of the Sun projected on the paper screen through the pinhole.
  4. To make the image of the Sun larger, hold the screen paper further away from the paper with the pinhole.
A box projector works on the same principles, it requires a little more time and a few extra items to construct, but it is more sturdy.
