While Baily's beads are seen briefly for a few seconds at the center of the eclipse path, their duration is maximized near the edges of the path of the umbra, lasting around 90 seconds. It is not safe to view Baily's beads or the diamond ring effect without proper eye protection because in both cases the photosphere is still visible. [5]
Those are known as Baily’s beads, named after English astronomer Francis Baily, who first observed the phenomenon during a total eclipse of the sun May 15, 1836. His vivid descriptions of the ...
Eerie skies, a glistening “diamond ring effect,” Baily’s beads and a halo around the sun are some of the phases to watch for during the April 8 total solar eclipse.

Francis Baily (28 April 1774 – 30 August 1844) was an English astronomer.He is most famous for his observations of "Baily's beads" during a total eclipse of the Sun. Baily was also a major figure in the early history of the Royal Astronomical Society, as one of the founders and as the president four times.
Pictured April 1, 2024 Brizard stands in front of images that show the diamond ring effect (left) and Baily's beads (right) which may be observable right before and right after totality on April 8.
The invention enhanced the precision for determining the time of an eclipse, due to more precisely timed photos of Baily's beads, [1]: 15 [2]: 284–285 and quantifying the duration of totality. This could not have been observed as closely as before due to the brightness of the sun. [1]: 15 [2]: 284–286
The image captured the progression of Baily’s beads. The phenomenon is visible for brief moments during an eclipse when sunlight shines through the moon’s valleys and craters, creating glowing ...
