Every 11 years or so, the Sun’s magnetic field flips, causing a cycle of increasing and then decreasing solar activity. During solar minimum, there are fewer giant eruptions from the Sun, such as solar flares and coronal mass ejections. But during solar maximum, the Sun becomes more...
This high dynamic range view shows off the intricate coronal detail that can only be observed during a total solar eclipse. The corona can be seen as long streamers reaching towards the edge of the frame as well as the loops and plumes closer to the sun's surface. They are affected by t...
Importantly, the event coincides with the solar maximum — a period of extreme activity that occurs every 11 years. During this time, the Sun’s magnetic fields intensify, creating sunspots, fiery loops of plasma and exciting structures in the corona. Access options Access Nature and 54 other...
ActivityWhiteDuring total solar eclipses, we can observe the outer atmospheric layers of the sun (chromosphere and corona). The solar corona extends to several solar radii depending on the sunspot cycle. Basic coronal structures such as polar streamers, helmet type structures were?observed?during ...
Check out the events at the bottom of this page for up-to-date details! As we get closer to the date of the eclipse, more information about special activities, viewing parties, and specials will be announced. One eclipse, a weekend of activity ...
The solar limb activity was studied during both of partial and total eclipse phases by using H-Alpha and white light observations from Salloum, Egypt. We got same prominence activity during partial and total phases of the solar eclipse and recorded three prominences on solar limb. Finally, our...
George Lovi (1939-1993), who was a longtime popularizer of astronomy and the night sky, once wrote: "One solar eclipse activity I hope to see less of is the sometimes ridiculous efforts to hunt down stars and planets during totality. Some devotees spend virtually all those precious minutes...
Solar maximum is predicted to occur in 2024, meaning more to see on the sun during the eclipse. Use your solar eclipse glasses during the partial phases of the eclipse, and you'll see sunspots— dark areas of magnetic activity — on the surface, close to its equator. If you're in ...
Eclipse-related outreach activities will abound this August, but how do we best capitalize on this rare celestial event after it happens?A Solar Eclipse Activity for a Sunny Day A fun activity to do with kids (or without) on a sunny day this summer to learn more about how eclipses work....
