“appalling splendour:” baily’s beads and the diamond ring effect during solar eclipses - aluminized mylar film
What exactly happened?
During the solar eclipse, the moon slowly covers the face of the sun.
The process takes about an hour or two.
Just before the sun completely disappears, several bright beads can be seen on the edge of the moon.
These lasted only a few seconds.
The last bead before the sun disappeared sparkled like a diamond, known as the diamond ring effect.
These effects occur because the sun's light ball or the last point on the surface is passing through the valleys and craters of the moon.
These phenomena are followed by the pink light of the Sun-colored ball, which is a layer of gas spike directly above the light ball.
An observer can even see the rise of the Sun, the flash of the plasma erupting from the surface of the sun.
After that, when the moon blocks the disk of the Sun, the corona or the corona can finally be seen.
This process is reversed when eclipse begins to end. eval(ez_write_tag([[250,250], 'Brighthub _ commedrectangle-

The best way to view eclipse should only be viewed through special filters, because some parts of it are too bright to view without damaging the eyes, especially when the sun is only partially covered by the moon.
Only when the diamond ring effect is over, eclipse will look at it safely.
When the diamond ring and Baily's beads return, the filter must be put on again, which marks the end of the solar eclipse.
A good, cheap filter is made of cardboard glasses with aluminum-containing Mella lenses.
Aluminum-containing mylar is mylar coated with aluminum film, which filters out all the harmful ultraviolet and infrared rays of the sun and almost all the visual light that may permanently damage the retina.
The buyer should check first to see if there is no hole in mai la and no tears.
The glass of the 14 th welder is also very nice.
A small hole camera that takes an image of a solar eclipse through a telescope passes through a piece of cardboard with a small hole on it, which is also very safe.
All of these filters can also be used to view sunspots.
Eclipses are not uncommon, but spectacular eclipses are not uncommon, but they are spectacular.
Partial solar eclipse occurs about three times a year, while total solar eclipse occurs about every 18 months.
Rare is the total solar eclipse that occurs in the same place on Earth in a short period of time.
The shadow or shadow of the moon is so small that it passes only a small part of the Earth.
The best case is that the track is barely over 150 miles wide, and the time when the sun is completely covered or completely covered will never exceed 7 minutes and 31 seconds.
Solar eclipse is possible, because the fascinating fact is that although the sun is 400 times the size of the moon, it is 400 times the distance from the Earth, so the moon can cover perfectly
During the solar eclipse, Baily's beads were not visible because the Sun had no chance to peek through the Valley of the moon.
Francis Bailey, an English astronomers, first described the beads.
He was born in Berkshire in 1774 and helped the Royal Astronomical Society.
Baily is such an important person in society. he was elected president four times.
Interestingly, astronomy began to be his hobby.
He initially worked on the London Stock Exchange and made a lot of money, so he was able to retire early and dedicate his life to astronomy.
On May 15, 1836, Baily saw the beads of his name in Roxburghshire's solar eclipse.
Solar eclipse means that during the solar eclipse, the shadow or shadow of the moon does not reach the Earth all the way, and there is a ring or ring, the light around the moon.
This happens when the moon is too far in orbit to fully cover the sun.
Baily's beads can be seen through this eclipse, sometimes a complete, beautiful necklace, but not a diamond ring effect.
Baily was in great awe of the incident, and his article on the incident inspired others to see the eclipse.
Baily himself went to Pavia, an ancient university town in Lombard, Italy, and in July 8, 1842, he saw the beads again during a total solar eclipse.
Two years later, he died in August 30, 1844.
