Here's some additional ways to view a Solar Eclipse without directly viewing the Sun. See these links:

* Hole Projector: https://www.timeanddate.com/eclipse/...projector.html

* Binocular or small telescope projector: https://www.timeanddate.com/eclipse/...projector.html

* Eclipse projector in a box: https://www.timeanddate.com/eclipse/...projector.html

* Leah, PAS Member, sends this info via email:
some tips for the partial stages of the eclipse - it is a good idea to prepare a pinhole projector. the instructions usually mention "two thin but stiff pieces of white cardboard". paper plates are very good for this, as well as box lids, or sides of a cut-up box (which don't have to be white). remember to stand with your back to the Sun when using this. you can practice on a non-eclipse day.

another projection method, not listed in the article is: look on the ground under a tree. the spaces between the leaves form many pinholes, and you will see a whole bunch of crescents as the sun is eclipsed. this makes a great photo. http://www.hartrao.ac.za/other/eclipse2002/pinhole.html

and another link, including step-by-step instructions for making a pinhole projection viewer: http://www.exploratorium.edu/eclipse/how.html

before the previous eclipse (annular eclipse in May 2012) I tried various methods and found that the "two pieces of cardboard" is easiest to use. you can even punch holes in a pattern (e.g. with the pinholes arranged to spell "PAS") and when you use it during the eclipse - each pinhole will show a view of the eclipsed Sun. great photo-op! in May 2012 I made one with the pinholes arranged to show the number 2012. a lot of nearby tourists took pictures of it. I'm including a photo.

if using a pinhole projector, it's a good idea to prepare it ahead of time, and try it out before the eclipse. you can try different size pinholes (anywhere from very tiny, to about 1/8 inch) and see what gives you the best effect. I made one with actual pinholes, and another with pinholes enlarged using a sharpened pencil (that's for the 1/8 inch). you can check that the pinhole is actually projecting, and not just showing a random circle of light, by taking a flashlight and covering part of the front; then try out your pinhole projector in a dark room to see if it shows the shape of the exposed part of the flashlight.

and in the meantime, here is the page from "MrEclipse.com" with everything you wanted to know about observing solar eclipses -

http://mreclipse.com/Totality2/TotalityCh11.html

and some info that we can use in a handout -

http://mreclipse.com/Special/SEprimer.html

and if you're planning to take photos, read the articles online (e.g. http://mreclipse.com/SEphoto/SEphoto.html and other articles on the MrEclipse page)

and *practice ahead of time* with a non-eclipsed sun. (all of the partial stages will be giving almost as much light as an uneclipsed sun, so it's important to practice exposure times.)

the day of the eclipse is NOT the time to start learning how to do it!

I also included pictures that I took during the annular eclipse in 2012. they were in the newsletter then too. my picture with the pinhole projector spelling "2012" is on p 10

Here are a few I found through a search engine:

1. https://www.nasa.gov/eclipselive

"Live video streams of the August 21 total solar eclipse, from NASA Television and locations across the country, will be available on this page.”

2. https://www.exploratorium.edu/eclipse

"You can watch it live on this website and on our free Android and iOS app​s, or come to the Exploratorium and join us for a special eclipse-day program.”

Note the iOS app is available from https://itunes.apple.com/us/app/tota...230195450?mt=8

And the Android app is from https://play.google.com/store/apps/d...alsolareclipse

3. https://www.timeanddate.com/live/

"Watch this space for our LIVE coverage of the total solar eclipse on August 21, 2017! Starting at 15:30 UTC (see corresponding US times), we will bring you live footage from multiple locations and real-time updates about the current location of the eclipse shadow and the progress of the eclipse in the US and worldwide.”
