Two partial solar eclipses await astronomy enthusiasts in 2022. 

The first happens at the end of April is best viewed from the southern tip of South America and the Antarctic.

The second partial solar eclipse of 2022 happens in October and is best viewed from Russia. Varying degrees of the sun’s disc are covered for observers in Europe, the Middle East, India, and northeast Africa.

This article will guide you through why a solar eclipse occurs in the first place, why they aren’t visible across the entire planet, and what you can expect while chasing the 2022 eclipses.

Solar Eclipses 2022

There are two partial solar eclipses in 2022, with the details set out below.

Partial Solar Eclipse | April 30, 2022

  • Partial eclipse visible from: Antarctica, central and southern South America.

The first partial eclipse of the sun this year lasts up to 2 hours when viewed from Antarctica, from 18:52 UT to 21:07 UT on April 30, 2022

This partial eclipse is relatively shallow, with just 52% of the solar disc covered by the moon at its height.

Because of this, the Sun’s disk will be visible at the eclipse’s maximum point, and neither the Sun’s corona nor the diamond ring can be seen.

The map below shows where the partial eclipse is visible from. The closer to the center, the more of the sun’s disc will be covered at maximum eclipse.

The outermost red line shows the limit for seeing any eclipse at all, i.e., outside of that, there is no eclipse visible. The next red line shows where 20% of the sun’s surface will be covered, and the innermost line is the 40% coverage limit. Nowhere on Earth’s surface sees more than 60% of the sun covered in this event.

April 30, 2021 – Annular Solar Eclipse Timings

  • First Place to See Partial Eclipse Start: 18:45 UT
  • Maximum Eclipse: 20:41 UT
  • Last Place to See Partial Eclipse End: 22:37 UT

As mentioned earlier, Antarctica will see almost half of the sun’s disc covered. Argentina and Chile will enjoy up to 52% coverage, Uruguay 11% and Brazil’s southwestern tip only 4%.

Total Solar Eclipse | October 25, 2022

  • Partial eclipse visible from: Russia, Europe, northeast Africa, Middle East, and India.

The second partial solar eclipse of the year is much deeper than the first with over 80% of the sun’s disc obscured by the moon when viewed from west of central Russia. The peak of this event lasts over 2.5 hours in Kazakhstan, from 09:43 UT until 12:35 UT.

The map below shows where the partial eclipse is visible from. The closer to the center, the more of the sun’s disc will be covered at maximum eclipse.

The outermost red line shows the limit for seeing any eclipse at all, i.e., outside of that, there is no eclipse visible.

October 25, 2022 – Partial Solar Eclipse Timings

  • First Place to See Partial Eclipse Start: 08:58 UT
  • Maximum Eclipse: 11:00 UT
  • Last Place to See Partial Eclipse End: 13:02 UT

What is a Solar Eclipse?

Solar eclipses are proof that daytime astronomical events can be as beautiful as the night ones. They occur when the Moon’s orbit places it precisely between Earth and the Sun, an alignment called syzygy (pronounced SIZ-eh-gee).

In doing so, the Moon blocks the sunlight, casting a shadow on Earth. If you’re standing in that shadow, you’ll see the Sun obscured to a greater or lesser extent.

Solar eclipses, where the Moon completely covers the Sun, happen due to a perfect coincidence of size and distance.

The Moon is 400x smaller than the Sun but is also 400x closer to Earth. This serendipity makes the lunar disc exactly the same size as the solar one from our perspective.

A solar eclipse begins when the moon makes its first contact, touching a limb of the sun and seeming to take a bite out of the perfect solar circle of light.

When the Sun is not totally covered, the eclipse is a partial one. As the partial eclipse progresses, the bite taken out of the Sun by the Moon grows gradually until the Sun is only a narrow crescent in the sky.

Ten-to-fifteen minutes before totality occurs is when the environment around you begins to change dramatically. There is a noticeable drop in brightness, the shadows grow sharper on the ground, and the sunlight will look strangely different, almost like you’re wearing shades.

A few seconds before the moment of totality, the last vestiges of sunlight peep through valleys between mountains on the Moon, causing the light to break into a thin string of beads, called Baily’s beads.

When totality hits, we instantly see our first glimpse of Sun’s corona, leading to the famous diamond ring effect. This is the stage where darkness takes hold too, making the brighter stars and planets visible in the daytime.

While the entire eclipse, from first to the last contact, lasts anywhere between one to three hours, totality itself lasts only for 2-5 minutes

All too soon Baily’s beads and the diamond ring will be visible once again as the moon begins to uncover the sun and the total solar eclipse reverts to a partial solar eclipse.

The disc of the Sun fattens once more as the Moon moves past and the eclipse comes to an end as the Moon’s limb touches the Sun’s in the final act of a solar eclipse, known as last contact.

Why is a Solar Eclipse Not Visible Across the Whole Planet?

The Moon’s shadow is only a few hundred miles across, which is nowhere near large enough to cover the entire Earth. This underlines the fact that you are very fortunate to observe a total Solar eclipse because the strip of Earth they can be seen from is so small.

Furthermore, the fact that only a tiny part of the Earth’s surface experiences an eclipse makes it extremely rare the same place will see a second eclipse within a human lifetime.

The Sun, Moon, and Earth are in constant motion in slightly elliptical orbits. Earth rotates around its axis while the Moon orbits the Earth, and their geometry changes with every eclipse, making it very rare for the same point on the surface of our planet to see consecutive solar eclipses.

What’s The Difference Between The Umbra and Penumbra?

In every eclipse that occurs, there are two shadows cast by the Moon, the inner, darker umbra, and the outer, lighter, penumbra.

It’s easiest to think of the umbra as the shadow we see when the whole Sun is covered, while the penumbra is the shadow caused by a partial covering of the Sun.

As you might imagine, the penumbra has different darkness levels. The part of the penumbra closest to the umbra, where the Sun’s surface might be >90% obscured, is much darker than at its far edge where the Sun is less than 10% covered.

If you stand inside the path of the umbra – also known as the path of totality – the Sun will be entirely blocked by the Moon and you’ll observe a total eclipse.

However, if you stand inside the penumbra during an eclipse, you will only observe it as a partial eclipse.

Of course, some solar eclipses are only partial. When this happens, there is no umbral shadow hitting the Earth’s surface.

While this post is meant to equip you with knowledge of when the eclipses occur, you cannot completely prepare for the splendor of these cosmic coincidences.

Eclipses give you a chance to watch the solar system at work right in front of your eyes; of the Moon around Earth and Earth around the Sun.

Irrespective of how many times you have seen it, the awe when an eclipse begins, the regret when it ends all too soon, and the ecstasy of witnessing it all cannot be jammed into strings of words. You can only experience it and store the bittersweet memory till the next one comes rolling in.
