Early morning: solar eclipse in Israel
Solar eclipse peak: at 5:47 when 54% of the Sun's diameter will be hidden by the Moon

The eclipse is an annular eclipse (when the size of the moon's disk is smaller than that of the sun) and it will be visible from Greenland and Iceland, northern and northeastern Europe and most of the northern part of Asia and Alaska. The peak of the annular eclipse will be at 5:08 Israel time and will be visible in Reykjavik, Iceland.

The chairman of the Israeli Astronomical Society Yigal Fat-El said that the sun will rise in Israel at 5:35 when it is weak, and about 50% of its diameter is hidden by the moon. The peak of the eclipse in Israel will occur at 5:47, when 54% of the sun's diameter will be hidden by the moon.

At the peak of the eclipse the sun will be only 2 degrees above the horizon. The eclipse will end in Israel at 6:41, when the last point of the shadow will leave the sun's disk.

The observatory in Givatayim will be open to the public starting at 5:00 am until the end of the eclipse and the public will be given explanations on the spot.
Fat-El said that the public must be careful and warned that viewing the sun is strictly forbidden, even through sunglasses, sooty glass, welder's goggles and in no way whatsoever.

Owners of small telescopes can project the image of the sun onto white paper and look at the image of the sun formed on the paper.

Light for Shabbat the sunrise will be one of a kind - the sun will rise when about 50% of its surface is covered by the moon.

A solar eclipse is an astronomical phenomenon that occurs when the Moon passes between the Earth and the Sun. The moon has no light of its own, and we see it because it is illuminated by the sun. During a solar eclipse, the moon hides a part of the sun, and therefore the sun's round disc appears to us to be "damaged".

To an observer on Earth, the Sun and the Moon appear to be of very similar (angular) size: the Sun is indeed much larger than the Moon, but it is also further away. Therefore, for an observer standing exactly on the continuation of the imaginary line connecting the Sun and the Moon, the Moon will appear to hide the entire disk of the Sun, or almost all of it. When the moon is slightly moved relative to the line connecting the observer with the sun, a partial solar eclipse will be seen.

Every year you can see between two and five solar eclipses from Earth. However, a solar eclipse is a local phenomenon. Each eclipse can be seen from a relatively limited area on Earth. That's why solar eclipses from Israel, or from any other point, are seen only every few years.

On the morning of Saturday, May 31, the sun will rise at 05:39 am. Unlike every morning, viewers watching the sunrise from Israel and Central Europe will witness a partial solar eclipse at a rate of about 50%. About eight minutes after sunrise, at 05:47, the eclipse will reach its peak (54% from central Israel), and an hour later, at 06:41 It will end. The next partial solar eclipse visible from Israel will occur on October 3, 2005.
One of the scientific uses made in the past of a solar eclipse resulted in the worldwide publication of Albert Einstein. One of the predictions of Einstein's theory of general relativity was that starlight passing near the rim of the Sun would be deflected to a certain extent by the Sun's large gravitational field. Therefore, the stars near the sun will appear to us to be slightly displaced relative to their normal position. In the past, testing the theory could only be done during a total solar eclipse, because in this state the strong light of the Sun is obscured by the Moon and you can see stars near it. In 1919, two expeditions led by Sir Arthur Eddington set out to measure the deflection of starlight near the Sun and their measurements confirmed Einstein's theory of general relativity for the first time.

It is absolutely forbidden to look at the sun with the eye, binoculars or a telescope without appropriate protective measures. Directly looking at the sun will cause serious damage to the eyes. Suitable protective measures are No. 14 welding glass or Mylar "paper". Carbonized glass, sunglasses and other standard means are not suitable for observing the sun, and their use may cause irreversible damage to the eyes.
