Sun's Corona To Be Visible On Total Solar Eclipse; NASA Shares Tips For Photography – News18

One of the rare phenomena that you can also witness is a coronal mass ejection.

A total solar eclipse is a phenomenon that occurs when the moon obstructs the Sun’s rays and blocks off the Sun’s view from Earth.

On April 8, a total solar eclipse will intrigue the viewers as the moon completely blocks the Sun’s rays from Earth, creating a brief period of darkness known as totality. During this extraordinary event, observers may catch a glimpse of the Sun’s corona, revealing dark-pink towers and loops of electrically charged plasma. Notably, similar prominences were witnessed during a total solar eclipse in Australia on April 20, 2023, impressing spectators with their spectacular display.

North America is set to experience these mesmerising prominences during the upcoming total solar eclipse. Reports from Live Science suggest that the event coincides with the peak of the Sun’s 11-year solar cycle, known as solar maximum. Even after the eclipse concludes, enthusiasts can use a hydrogen alpha telescope to observe these prominences for several days afterwards. Additionally, observers are encouraged to remain vigilant for other rare phenomena during totality.

One such phenomenon is a coronal mass ejection (CME), described by a solar physicist from the National Solar Observatory in Boulder, Colorado, USA. These CMEs appear as twisted, spiral-like structures high in the Sun’s atmosphere, comprising magnetic fields and plasma mass ejected from the corona. Despite their rapid movement, CMEs may appear stationary, offering a sight visible from locations such as Rochester and Dallas, albeit at different stages of the same eruption.

Solar flares, another remarkable occurrence, are powerful bursts of radiation emitted from the Sun’s surface at the speed of light. While the likelihood of witnessing a solar flare during totality is minimal, they often follow CMEs and can reach Earth in just eight minutes, providing a fascinating celestial display.

Eclipse chasers eagerly await the opportunity to observe giant eruptive prominences during totality on April 8. These prominences, varying in size, are most commonly observed during solar maximum and may even detach from the Sun’s surface, floating freely within the corona.

In summary, the total solar eclipse on April 8 promises to offer not only a breathtaking display of the Sun’s corona but also opportunities to witness rare celestial phenomena, captivating observers across North America and beyond.
