Do you remember the world’s last total solar eclipse in August 2017? Millions of people observed the eclipse as it passed over parts of the United States. Why did so many people flock to certain parts of the United States to witness this astronomical feat? Because a total solar eclipse is a rare event. Before the August 2017 solar eclipse, it had been 38 years since a total solar eclipse was visible from North America.
The next total solar eclipse will happen on July 2, 2019. Unlike the August 2017 solar eclipse, the July 2019 total solar eclipse can only be seen by those who are in Chile and Argentina. According to an online article from VOA News, “Local officials say they expect more than 400,000 visitors to come to the area.”
Why Is Seeing a Total Solar Eclipse So Important to People?
A total solar eclipse is rare and lasts only a few minutes. NASA estimates that the sun will be eclipsed by the moon for as long as four minutes and 33 seconds. The European Southern Observatory estimates that most areas on earth sees just one solar eclipse, on average, every 360 years. However, lucky for many North American areas, another chance to see a total solar eclipse will be on April 8, 2024.
How Can I Safely View a Solar Eclipse?
Although the total eclipse won’t be visible from the United States in July 2019, we wanted to share a few tips that provided. You can keep these tips in mind as you prepare for the April 2024 eclipse:
“The only safe way to look directly at the uneclipsed or partially eclipsed sun is through special-purpose solar filters, such as “eclipse glasses” or hand-held solar viewers. Homemade filters or ordinary sunglasses, even very dark ones, are not safe for looking at the sun; they transmit thousands of times too much sunlight. Refer to the American Astronomical Society (AAS) Reputable Vendors of Solar Filters & Viewers page for a list of manufacturers and authorized dealers of eclipse glasses and handheld solar viewers verified to be compliant with the ISO 12312-2 international safety standard for such products.
Note: If your eclipse glasses or viewers are compliant with the ISO 12312-2 safety standard, you may look at the uneclipsed or partially eclipsed Sun through them for as long as you wish. Furthermore, if the filters aren't scratched, punctured, or torn, you may reuse them indefinitely.”
We hope these safety tips give you ideas on what you’ll need for the April 2024 eclipse or the July 2019 eclipse, if you are lucky enough to get to witness it.
