SOLAR ECLIPSE. A partial solar eclipse was visible all over Europe and part of Asia on Tuesday, October 25, 2022. However, it was not visible in the same way depending on the city, depending on the rate of obscuration.
[Mis à jour le 25 octobre 2022 à 21h11] Tuesday, October 25, an eclipse of Sun was visible in the sky in France. It occurs when the Moon is placed between the Earth and the Sun, partially or totally hiding the latter. This morning it was a partial eclipse could be seen in the hexagon. Nevertheless, the Sun has not been hidden in the same way depending on the region. Indeed, it was in the east of the country that the partial eclipse was most visible. In Strasbourg, the obscuration rate was almost 20% (19.5%) at 12:09 p.m. On the contrary, in the southwest, in Pau, the obscuration rate was only 3.5% at 12:02 p.m.
Even at the peak of the eclipse, over Kazakhstan, the Sun was over 80% hidden. An insufficient figure to have a perception of darkness in broad daylight, since it requires an obscuration of at least 95% of the Sun. Discover the best photos of the solar eclipse around the world, and below, some spectacular tweets of photos taken in France:
What was the percentage of occultation according to the city of France where you were? How to explain the phenomenon of solar eclipse, total or partial? What are the next eclipses in France and around the world? Learn all about it in the file below.
The solar eclipse of October 25, 2022 was partially visible in France, obscuring only 2.8% of the surface of the Sun in Biarritz while in Strasbourg, the covered surface was 19%. Here is the percentage of occultation of the solar eclipse according to the city where you were (IMCCE data):
- Paris : 13.7% occultation by the Moon.
- Lille : 17.2% occultation by the Moon.
- Caen : 11.4% occultation by the Moon.
- Quimper : 6.2% occultation by the Moon.
- Metz : 18.4% occultation by the Moon.
- Strasbourg : 19.5% occultation by the Moon
- Dijon : 14.4% occultation by the Moon.
- Nevers : 11.8% occultation by the Moon.
- Poitiers : 8.3% occultation by the Moon.
- Nantes : 7.4% occultation by the Moon.
- Bordeaux : 5.1% occultation by the Moon.
- Aurillac : 8.1% occultation by the Moon.
- Lyons : 11.8% occultation by the Moon
- Avignon : 9.3% occultation by the Moon.
- Paul : 3.5% occultation by the Moon.
- Toulouse : 5.4% occultation by the Moon.
- Perpignan : 5.7% occultation by the Moon
- Nice : 11.7% occultation by the Moon
- Ajaccio : 11% occultation by the Moon.
To observe the solar eclipse with the naked eye, it is imperative to wear special glasses. Conventional sunglasses are not sufficient to protect the retina. During the eclipse, with the decrease in luminosity, the pupils will tend to dilate. When the sun suddenly reappears, serious retinal damage can occur. These burns are not painful, so special care should be taken.
Tricks like looking at the eclipse through a CD or through smoked glass are not effective. To protect your eyes and make the most of the eclipse, go to an astronomy club where you can observe the eclipse indirectly by projection. The simplest solution: make a small hole in a piece of cardboard, direct it towards the sun and observe the projected eclipse. Be aware that glasses allowing you to observe the eclipse without danger are available for around 2 euros. It is also possible to buy them in shopping centers or in stores such as Nature et Découverte, or to order them on the Internet. All the tips are in our file below:
A solar eclipse occurs when the Earth, Moon and Sun are perfectly aligned in the same plane. The Moon then casts its shadow on the Earth, thus masking the Sun, and plunging part of our planet in the dark for a few minutes.
The Earth revolves around the Sun in a plane called the “plane of the ecliptic”. The Moon on its side revolves around the Earth in another plane. So at new moon, when our satellite is located between the Earth and the Sun, it is usually not perfectly aligned with them. This is why there is no solar eclipse every new moon. Exceptionally, all the conditions are met: Earth, Moon and Sun are aligned in this order on the plane of the ecliptic. A solar eclipse then occurs.
A partial solar eclipse occurs when the Earth-Moon-Sun alignment is not perfect, when the Moon passes slightly above or below the Earth-Sun alignment. The Moon comes to hide only a piece of the Sun, which is not enough to completely darken the sky. “To start to have a feeling of darkness in the sky, to perceive a kind of cold light, you need at least 95% obscuration of the Sun,” said AFP Florent Deleflie, astronomer at the Paris Observatory. . This astronomical phenomenon of partial solar eclipse, which occurs when the Sun, Moon and Earth are imperfectly aligned, does not darken the sky and is observable only with protections adequate, under penalty of “irreversible retinal burns”, warns Florent Deleflie, of the Paris Observatory.
Find all the dates of the next total solar eclipses in the world, but also partial and annular ones in France, in our file below.
The next solar eclipses visible from France will be partial. A partial eclipse shows only part of the Sun obscured by the Moon. They will be visible in France on the following dates: March 29, 2025 and the August 12, 2026.
The previous solar eclipse in France dates back to June 10, 2021. Did the French have the chance to observe a thin ring of the Sun covered by the black disc of the Moon? In metropolitan France, the eclipse presented the sun only masked from 0.2 to 17.8% by the Moon.
An extremely rare phenomenon, a total solar eclipse only occurs when the Sun, Moon and Earth are perfectly aligned. A total solar eclipse will not occur until September 3, 2081 in France. French astronomy enthusiasts will have to be patient… More precisely on September 3, 2081, followed by a second complete eclipse on September 29, 2090. In the meantime, it will still be possible to see the Moon partially occult the Sun.

Photographing a solar eclipse: what settings and what equipment?
If you want to enjoy the spectacle of a total solar eclipse in Europe, you will have two chances to see one… In 6 years! On August 12, 2026 turn first, darkness will cover northern Spain and parts of Iceland. This total solar eclipse will only be partially visible in France. The following year, on August 2, 2027, a second total eclipse will be visible in the far south of Spain. If you stay in France, you can still enjoy a very beautiful partial eclipse.
Between the partial and total eclipse, the annular eclipse occurs when the Sun and the Moon are perfectly aligned with the Earth but the apparent size of the Moon is slightly smaller than that of the Sun. This then forms a bright ring surrounding the lunar disk. The next annular eclipses will be completely visible from France on the following dates: November 5, 2059 then February 27, 2082.
On Saturday April 30, 2022, a solar eclipse was visible only from Antarctica, the Pacific and South America. The French were able to observe it only from the NASA YouTube channel.
