This Saturday (19), there is a Sun’s partial eclipse visible only from the northern hemisphere and invisible to Brazil.
Eclipses happen when an object in space, like a planet or moon, goes through the shadow of another celestial body in space. On Earth we can see the lunars and solar.
During a solar eclipse, it is the moon that places itself between our planet and the sun, blocking the sun’s rays to reach the earth.
One Total Sun Eclipse It occurs when the moon, the sun and the earth position themselves perfectly in a straight line, allowing the moon to block virtually all the sun’s rays that would arrive on Earth and make the day turn night for a few minutes. Node partial eclipse The three celestial bodies do not align themselves perfectly, causing the moon’s shadow to cover only a part of the sun – which seems to have taken a “bite.”
The central part of the shadow of the moon – the one that causes the total eclipse – will not reach Earth in this Saturday’s phenomenon (29), making everyone see eclipse partially on our planet.
According to NASA, partial solar eclipses occur at least twice a year in some place on Earth. Total solar eclipses happen on average every 18 months somewhere on the planet – hardly in the planet.
Generally, solar eclipses occur more often in places closer to Earth’s poles.
Phases of a partial eclipse of the sun
There are three phases in a partial solar eclipse:
- Start : When the moon begins to move on the solar disk.
- Maximum eclipse : Eclipse reaches its magnitude Maximum, that is, the “bite” in the sun is larger than any other time of the eclipse.
- End : The moon follows its way and stops covering the sun.
This Saturday (29), the partial eclipse of the sun will reach its maximum at 7:59 and will end at 9:34 am (BrasÃlia time).
Observing tips for a solar eclipse
- Do not look at the sun without protection;
- If you are where the phenomenon will be visible, know that it is not safe to look at a solar eclipse without suitable equipment, as this can cause serious eye injuries;
- Nor is it recommended to see it by camera lenses, binoculars or telescopes without a suitable filter;
- The ideal is to use ISO 12312-2 standard lenses, which are not present in normal sunglasses. Remember that ordinary sunglasses are not safe to look straight into the sun, no matter how dark the lenses are.
- Accessories can be purchased even over the internet, but it is important to make sure they comply with safety standards;
- If on eclipse day you do not have a safe equipment to observe the phenomenon, another possibility is to resort to indirect observation, made through a projection.
