On Monday, April 8th, people across North America witnessed a rare celestial event known as a total solar eclipse. This phenomenon occurs when the Moon passes between the Sun and Earth and blocks the face of the Sun for a short period. The eclipse plunged the sky into darkness for people living in the Canadian Maritimes, the American Eastern Seaboard, parts of the Midwest, and northern Mexico. Fortunately for all, geostationary satellites orbiting Earth captured images of the Moon’s shadow as it moved across North America.

Eclipse-gazers across the United States got a chance last weekend to watch as the Moon aligned with the Sun to create an annular eclipse. They watched from the ground for a short experience of not-quite-darkness. NASA’s Deep Space Climate Observatory (DSCVR) caught the action from Earth orbit for a different view of the event.

Remember how exciting it was in 2017 when a total solar eclipse crossed the United States? We’re in for two more well-placed eclipses over the next year, so it’s time to get organized to take advantage of these unparalleled celestial events.

On October 14, 2023, an annular eclipse will be visible to millions of people in the US, crossing northwest to south central, from the coast of Oregon down to the Texas Panhandle.

Then, on April 8, 2024, a total solar eclipse will be visible to millions more, crossing south central to northeast, from southern Texas to Eastern Canada. It will be visible in parts of Mexico, too.

Now is the time to make plans of where you want to be for either or both events. But, if you live near San Antonio, don’t go anywhere! You’ll get to see both eclipses right from your backyard.

No matter where you live, if you have the opportunity to see a solar eclipse – whether it is annular or total – DO IT!

Did the skies above you cooperate this morning to see the total lunar eclipse? Mine did not, and Fraser reports he was clouded out as well. But thankfully, we can live vicariously through all of the wonderful friends and astrophotographers who have shared their jaw-dropping photos of the blood Moon, Beaver Moon total lunar eclipse. This is the last total lunar eclipse until March 14, 2025.

Our lead image, a composite from University of Arizona Professor Eliot Herman shows a series of views throughout the eclipse. “This Lunar eclipse had soft gradations of color that was quite beautiful,” Herman said on Flickr. “This series of photos begins just before totality and ends just after totality. All images are 15 images stacked captured with a Questar telescope, Baader UV/IR filter, and a Nikon Z7II.”

If you were able to witness the lunar eclipse on May 15-16, 2022, the view of the dark red Moon was stunning. But what would such an eclipse look like from space?

Wonder no longer. ESA/Italian astronaut Samantha Cristoforetti captured a series of photos of the lunar eclipse from her unique vantage point aboard the International Space Station (ISS).

People across the northern hemisphere looked up today – taking the correct precautions, of course – and were treated to a partial solar eclipse. The partial eclipse covered a region thousands of kilometres wide across most of Europe, northern Asia and north central and north eastern North America. An annular or “ring of fire” solar eclipse was visible to some parts of Greenland, Northern Russia, and Canada.

Our unique lead image comes from Andrew Symes from Ottawa, Canada, who took this photo with his iPhone 11 Pro through his Celestron NexStar 8SE telescope, providing a fun and interesting look at his view of the eclipse!

On July 2, 2019, the Moon cast its shadow on the surface of the Earth. This time, the shadow’s path travelled across the South Pacific Ocean. It also passed over some of Argentina and Chile. For surface dwellers in the path, the Moon briefly blocked the Sun, turning night into day.

But for one “eye” in orbit around the Moon, the view was different. A camera on a tiny satellite watched as the circular shadow of the Moon moved over the Earth’s surface.

How about that Total Lunar Eclipse this past July 13th? It has been a busy year for astronomy for sure, with two total lunar eclipses, a comet fading out from an unexpected burst of glory, and Saturn, Jupiter and Mars reaching opposition in quick succession.

Now, watch for a rare event this weekend, with the final eclipse for 2018 coming up on Saturday, August 11th, with a partial solar eclipse spanning northern Europe and the Arctic.

What’s so unique about this eclipse? Well, not only is it the last one for 2018, but it’s part of three eclipses in the second eclipse season of the year. Most seasons only feature two eclipses (one lunar and one solar) but every few years or so, it is possible to have a season with three: either lunar-solar-lunar (such as occurred in 2013) or solar-lunar-solar.

This is only possible when the middle eclipse occurs very near ascending or descending node along the ecliptic. The nodes are where the path of the Moon, inclined 5.1 degrees relative to the ecliptic plane intersect it—when these nodes are occupied by an alignment of the Earth, Sun and Moon (known as a syzygy, a fine word in Scrabble to land on a triple word score, though you’ll need a blank tile for the third ‘y’) a solar or lunar eclipse occurs. For an eclipse triple play, the middle eclipse needs to happen very near a node crossing, producing a fairly long eclipse. That’s exactly what happened on July 28th, when the Moon crossed through descending node just over an hour after crossing out of the Earth’s umbral shadow after the longest lunar eclipse for the 21st century.

This also leaves the Moon close enough to the opposite ascending node two weeks post and prior to July 28th on July 13th and August 11th to just nick the Sun for a partial solar eclipse, one over the Antarctic and one over the Arctic.

Eclipse Circumstances

Saturday’s partial eclipse touches down over the eastern coast of Canada at sunrise. From there, it sweeps eastward over Greenland, Iceland and the North Atlantic, with the Moon’s penumbra just grazing the northern United Kingdom before crossing over Scandinavia. Then, the shadow crosses over Asia, with a photogenic partial solar eclipse wrapping up at sunset over eastern China, the Koreas and the Russian far east.

Note that this eclipse is also a relative newcomer for its particular saros 155, as it is member 6 of a series of 71 eclipses. The saros just began less than a century ago on June 17th, 1928, and won’t produce its first total solar eclipse until September 12th, 2072 AD.

As of this writing, we’ve yet to see evidence of anyone carrying the eclipse live, though we’ll note it here if any webcast(s) surface.

When is the next one? Well, the next partial solar eclipse is on January 6th 2019, and the next total solar eclipse occurs on July 2nd, 2019.

Enter the Perseids

This weekend’s eclipse at New Moon also sets us up for a fine display of the Perseid meteors for 2018. This year, the Perseids are expected to peak on the morning of August 12th and August 13th. Watch for a zenithal hourly rate of 100 meteors per hour at the peak. A dependable annual favorite, the Perseids are debris remnants of period comet 109/P Swift-Tuttle.

Astronomer Gianluca Masi and the Virtual Telescope Project 2.0 will host a live webcast for the 2018 Perseids on August 12th starting at 20:30 UT.

Don’t miss the astronomical action worldwide this weekend, either live or online.

A Partial Solar Eclipse Down Under

Eclipse season in nigh… though most of us won’t notice the start this week. The second eclipse season for 2018 commences with the arrival of New Moon and Brown Lunation number 1182 at 3:01 Universal Time on (triskaidekaphobics take note) Friday July 13th, 2018. This eclipse is a shallow partial, just skimming the southern hemisphere of the Earth between the Australian and Antarctic continents.

The Eclipse

We doubt many eclipse chasers will make the pilgrimage to Tasmania to see such a slim partial, though we know of at least one, veteran eclipse chaser Jay Pasachoff who has expressed intent on the Yahoo! Solar Eclipse Message List (SEML) message board to head southward this week.

Tasmania gets the best view, with a maximum 9.5% obscuration of Sol as seen from the capital Hobart around 3:25 UT. The upper limit of the eclipse path just skims the southern coast of Australia across the Great Australian Bight and the southern Indian Ocean, and nicks the very southern tip of the south island of New Zealand and Steward Island at 3:48 UT with a barely discernible 1% eclipse before the lunar penumbra departs the Earth. If skies are clear, the very best view just might come along the coast of Antarctica, as the 33% eclipsed Sun rolls along the northern horizon.

Perhaps a few lone penguins will notice, if they bother to look at the Sun filtered through the murk of the atmosphere along the horizon. France does have one permanently occupied research station in Antarctica named Dumont D’urville along the coast that will see a 30% eclipsed Sun on the horizon right around 3:00-3:15 UT.

We say that this heralds the start of eclipse season, as the ascending node where the Moon’s orbit intersects the ecliptic plane is very near the current position of the Sun. In fact, node crossing occurs at 18:50 UT on July 13th, just 24 hours after New Moon. Eclipses always occur in at least pairs, and the Full Moon two weeks later is close enough to the descending node for a nearly central total lunar eclipse on July 27th (more on that in a bit). This season, however, is special, with a third eclipse ending the cycle on August 11th, 2018, this time gracing the Arctic pole of the Earth along with Scandinavia and Russia.

We’re already seeing some hype surrounding this event as a “Supermoon eclipse,” as the Moon reaches perigee 5 hours 27 minutes past maximum eclipse. Note that this also sets us up for a Minimoon total lunar eclipse two weeks later, as the Moon is near apogee on July 27th.

The Moon’s orbit is tilted 5.145 degrees relative to the plane of the ecliptic, and the nodes make one full revolution around the Earth relative to the equinoctial points once every 18.6 years in what’s known as the precession of the line of apsides.

Viewing a Partial

A partial solar eclipse means that all safety precautions must be taken throughout all phases of the eclipse. This means using approved solar filters that fit snugly over the aperture of a telescope, and solar glasses with the approved ISO 12312-2 rating for solar viewing. We built a safe binocular filter out of a set of spare eclipse safety glasses for the August 21st, 2017 total solar eclipse last year.

Unfortunately as of writing this, the disk of Sol is blank in terms of Earthward facing sunspots, and may be so on eclipse day. We’re currently headed towards a profound solar minimum and the Sun has already been spotless for more than half of 2018 thus far.

Don’t own a solar filter, safety glasses or a telescope? You can always use our tried and true method of projecting the eclipse using a spaghetti strainer.

It’s all in the gamma. This eclipse is partial only, because the dark inner shadow or umbra misses the Earth by 35.4% of the radius of the planet or about 1,400 miles. The gamma for an eclipse states how many Earth radii an eclipse deviates from central (where the Moon’s umbra is aimed straight at the center of the Earth) and Friday’s eclipse has a gamma value of 1.3541.

Tales of the Saros

Friday’s eclipse is part of an older saros series, member 69 of 71 eclipses for saros series 117. This saros started waaaaaay back on June 24th, 792 AD, and produced its last total solar eclipse on May 9th, 1910. This was also the last total solar eclipse for Tasmania until June 25th, 2131. This series only has two more eclipses to go, with its last event occurring briefly over the Antarctic on August 3rd, 2054. Perhaps, Friday’s event will be the very last one witnessed by human eyes for saros 117.

This also sets us up for the best of the three eclipses this season, the total lunar eclipse at the end of the month on July 27th. This eclipse will be widely visible across Africa, Europe, Asia and Australia—only the Americas miss out.

A Possible Views… “From Spaaaaaaace…”

The International Space Station also threads its way through the outer shadow of the Moon towards the end of the event Friday at ~3:50 UT. ESA’s solar observing Proba-2 spacecraft might just get a very brief view as well from its vantage point in low Earth orbit, around 3:09 UT.

And although most of us miss out on Friday’s eclipse, you can still try and spot the slender crescent Moon on the evening of Friday, July 13th. The U.S. East Coast is particularly well placed to try and spy the slim Moon low to the west, only 22 hours after New. After that, the Moon tours all of the naked eye planets, passing Mercury and Venus this weekend and passing Jupiter, Saturn and Mars en route to the July 27th total lunar eclipse.

Will anyone webcast the eclipse live? So far, no webcasts (not even from the venerable Slooh site) have surfaced… if anyone else is planning on featuring the July 13th partial solar eclipse, let us know!

It’s the biggest question when it comes to solar eclipses. When’s the next total? Well, just under a year from now, the next total solar eclipse crosses Chile and Argentina on July 2nd, 2019. Note that this event crosses over several major astronomical observatories at La Silla. How many newly minted eclipse chasers fresh off last year’s Great American Eclipse experience can’t wait until totality next visits the United States on April 8th , 2024 and plan to head to South America next summer?

A partial eclipse may not inspire many eclipse chasers to hop on a plane, but we can still marvel at the celestial ticks of a clockwork Universe carry on, right on schedule.
