Solar Eclipse Eye Safety

We are a bit over 2 months away from the eclipse, so I thought that this was as good a time as any to review eye safety details with you. 

Here is the most important thing to remember from this post: anytime the sun is not covered at all, or partially covered (even including 99%!) you MUST use proper methods AND proper materials to PROTECT your eyes. However, if you are in this path of totality:

then DURING THE TOTAL PHASE ONLY, WHEN THE SUN IS COMPLETELY BLOCKED, it is COMPLETELY SAFE to look at the sun directly without any protection. If you try to use eye safety protection during totality, you'll miss the best part!
When the sun returns, you MUST go back to the proper eye safety methods and materials. 
So, how do you keep your eyes safe before and after the eclipse, as well as during the partial eclipse (or partial phases before and after totality)?
Well, I'll just let the American Astronomical Society tell you:

Notes:
Safe solar eclipse glasses and viewers must comply with the ISO 12312-2 international standard.
Reputable suppliers of safe (non-magnified) solar viewers:

Based upon comments that I see on social media, I feel I must emphasize this part, from the website:
"Important: We do not recommend searching for eclipse glasses on Amazon, eBay, Temu, or any other online marketplace and buying from whichever vendor offers the lowest price. Before you buy a solar viewer or filter online, we recommend that you make sure that (1) the seller is identified on the site and (2) the seller is listed on this page."
If you are intending to watch with magnification, see also:

Also note the section on projecting the sun's image. There are multiple ways to do that- just make sure to follow the recommended procedures. Seeing eclipse crescents projected by the trees is a great way to experience the partial phase not long before totality!
Have a great (but safe) view.

The Total Solar Eclipse Checklist: What to look for!

The topic of this post is a checklist of what to look for if you are experiencing the eclipse. It’s primarily aimed at those who are in the path of totality, but some of this information can be used by people who will be experiencing a partial eclipse. I refer you to my earlier descriptive post on what happens during a total solar eclipse:  https://eclipse482024.blogspot.com/2022/04/an-incredible-experience-is-coming.html Also, of course, this assumes you know the eye safety rules. Before the eclipse begins, or during ANY part of the partial, you have to protect your eyes using proper methods and materials. But totality is COMPLETELY SAFE TO LOOK AT WITHOUT PROTECTION.   Realize that these changes don't even really begin until a large portion of the sun is covered, and that they are subtle at first. Then, they are noticeable but not dramatic. It's only shortly before totality that things become really dramatic. That's one of the many incredible things about totality- it tak...

Choosing a specific observing location

Today, I'll be covering the topic of choosing an observing location within the path of totality. You don't necessarily have to plan well in advance which exact location from which you'll watch the eclipse, but it might be a good idea to consider which factors are most important to you. Here are some things that you may want to think about:   Most Important   1.   (obviously!)   The observing location must be within the zone of totality. If you're outside the main shadow path (even by a short distance!) you won't see the sun completely blocked, and you'll wonder what the excitement was about. See my previous blog posts about this! As a reminder, the totality path is in between the red lines on this map, courtesy of Xavier Jubier:  http://xjubier.free.fr/tse2024map   2. (obviously!)  Make sure the location that you pick does not have something (hills, trees, tall buildings) that may block the Sun at eclipse time.  The Sun will be about 60...

Blog posts classified by category

Since we are just a few days away from the eclipse, I thought I would post this to help find my blog posts a little bit easier, organized by category. Just in case you wanted to do some final “studying” this weekend! There is an archive on my blog page in the menu, or you can just browse through the whole blog. I’m also happy to do whatever I can to make things easier for you. Some of the topics I have not posted yet. I will put the topic in the category and when I make the post, I will edit this to include the link.
