I’m pretty darn excited. I’ve never seen a total solar eclipse, and I’m getting my first chance to do so, along with many, many residents of North America, on August 21st. I’m heading back to the St. Louis area to see my friends from my post-doc days, visit an elementary school with some cool activities, and chase away the clouds (I hope!) and see my first total solar eclipse. If you’re in the North and Central America, and even parts of South America, you’ll be able to see at least part of an eclipse, so get ready!
There are lots of LOTS of people who have been working hard to make sure that folks get to see the event safely. No, you should NEVER LOOK DIRECTLY AT THE SUN without proper equipment. That said, looking at the Sun during an eclipse is no more dangerous than looking at the Sun any other day. It’s just a concern because so many people want to look up! You don’t need expensive equipment, but solar viewers are highly recommended for looking up. The American Astronomical Society has a good primer on eye safety PLUS a page full of reputable vendors that will actually keep your eyes safe from the infrared, visible, and ultraviolet light from the Sun while you view. Obviously, there has been a rush on these things, but you can call your local library, since many have been stocked with cheap and free glasses just for this.
Don’t have time to get solar viewers? That’s okay! Indirect methods work as well. Science Friday has FIVE DIY ways to view the eclipse with little to no cost.
Going to the path of totality? Great! It’s going to be PACKED. I’m already a little nervous about it, as towns are expecting gridlock as people swarm to be in the path of totality. Take the advice of Angela Speck, astronomer at the University of Missouri who lives right on the path, and pack water, food, and emergency supplies when you head out on the 21st. Also? Make sure to gas up your vehicle the day before.
You all know how I love citizen science, where everyone can take part in data collection an analysis. This eclipse is providing many such opportunities for doing citizen science, including tracking atmospheric conditions, logging animal behavior, and investigating the ionosphere with radio waves.
As for me? I’m just going to watch and enjoy since it’s my first. I’ve been advised by several experienced eclipse watchers to just enjoy the experience. I took that advice to heart when I saw my first space shuttle launch, and I’m so glad that I did. Totality is super quick, just under two minutes depending on your location, so I plan to soak it all in!
If you’re not on the path of totality, you never really get full darkness, and the Moon will take its time to cross the solar disk. So, you can view at your leisure. I really love this visual by Vox where you can put in your zip code and see when the eclipse will take place, and at what percentage, wherever you are. So plan your day around it if you can!
