The once-in-a-lifetime spectacle will attract an estimated 7.4 million people to areas in the path of totality, including so-called eclipse-chasers, who plan for years in advance and travel from far and wide to get a glimpse of the stellar phenomenon.
This video, narrated by actor George Takei, provides a few viewing tips for the public.
"During the August 21, 2017 total solar eclipse, scientists will use the Earth Polychromatic Imaging Camera (EPIC) on the Deep Space Climate Observatory satellite (DSCOVR), along with measurements taken from within the moon's shadow on the ground, to test a new model of Earth's energy budget."
On Monday 21 August only some countries North America, Australia, began school time. Not European countries. Not France or French Antilles.
Even so, teachers had prepared students to understand this incredible moment and will join astronomers on NASA streaming, skywatchers, or national observatories of Astronomy.
Remember your students ! DO NOT look directly at the Sun without appropriate protection, such as special eclipse glasses.
Special glasses that ensure sun spotters do not damage their eyes. Good solar eclipse glasses filter out all of the harmful ultraviolet and infrared light and almost all of the intense visible light to allow you to view the eclipse safely.
But thousands of people across the world are in the precess of building their own viewers. Children should get an adult to help build and use this projector. Take extra care when using sharp tools like craft knifes and scissors.
The safest way to view a solar eclipse is to project it onto a piece of paper. Using a cardboard box, you can make a pinhole projector.
Teachers must consider the activities to every level or curriculum they are teaching. Invite your students to share their experiences on Twitter, Facebook, Instagram (school or class account) during the event.
After summer holidays, European achools will discuss their experiences and knowledge if they could watch the partial eclipse. Not so lucky as North American schools.
"The Eclipse Megamovie Project is gathering images of the 2017 total solar eclipse from over 1,000 volunteer photographers and amateur astronomers, as well as many more members of the general public. We’ll then stitch these photos together to create an expanded and continuous view of the total eclipse as it crosses the United States. The resulting dataset will be open to the scientific community and general public for future research."
Apps: Apple; Google Play iTunes: The Eclipse Megamovie Mobile app from the Space Sciences Laboratory at UC Berkeley and Ideum is specifically designed to help you students, teachers, skywatchers view and photograph this incredible event and link them to a nation wide citizen-science project studying the sun. The app also helps you plan ahead with information about the best route from your location to the eclipse’s path and a countdown clock ticking down to the big event. And if you use a DSLR to capture the eclipse, your images may become part of a stunning crowd-sourced movie created by Google.
Led by Google, the Eclipse Megamovie Project will add a new dimension to our studies of the sun’s faint outer atmosphere – the corona. Corona is Latin for, “crown,” but in astronomy, it is an aura of plasma that explodes and arches out the Sun. The plasma corona extends millions of kilometers into space from the Sun and is easiest to see during a total solar eclipse or with a coronagraph.
