Lee este articulo en español.

Most people who live in North, Central, or South America will experience an annular or “ring of fire” eclipse on 14 October 2023! On this day, the Moon will move between the Earth and Sun, blocking all but a glowing ring of light for several minutes. What happens in the atmosphere when the Moon blocks the Sun’s light, even briefly? GLOBE invites everyone to help answer that question by recording changes in temperature and sky conditions on 14 October, even if you are only experiencing a partial eclipse. The updated GLOBE Eclipse tool is available in practice mode now in the app! (Visible to users in North, Central, and South America.)

Your observations during an eclipse can help us better understand our atmosphere, as described by GLOBE Clouds project scientist Marilé Colón Robles and Dr. Brant Dodson in the short reel below, and in the longer blog post An Astronomical Atmospheric Experiment: A Backyard Astronomer's Guide to Experiencing a Solar Eclipse.


We hope you will join us in collecting data on 14 October 2023!
