Want to see a total solar eclipse? Here’s how to plan for it, and how to set your expectations in case of clouds

This week, eclipse chasers shall be visiting the small city of Exmouth, on the tip of North West Cape in Western Australia. Climate allowing, they’re coming to see one in all nature’s best sights—a total eclipse of the sun on Thursday April 20.

Whether or not staying at motels, resorts or tenting websites, many would have made journey preparations a yr or extra prematurely. However do not be too disillusioned if you cannot be there; different alternatives to see total eclipses are developing within the subsequent few years. This is what you’ll want to know.

A completely immersive expertise

A total solar eclipse happens on these uncommon events when the Moon traces up with the sun and passes in entrance of it from our vantage level right here on Earth. The intense disk of the sun is solely hidden for a brief interval—seconds or minutes. Throughout this time, known as the totality, eclipse watchers will see a darkish gap within the sky the place the sun had been, surrounded by a faint glow—our star’s corona.

That is what eclipse chasers search to witness. The string of areas the place a total eclipse shall be seen to observers known as the “path of totality.” Individuals will usually journey hundreds of kilometers to be in the precise place on the proper time. They don’t seem to be solely handled to the magnificent sight of the corona, however get a completely immersive expertise.

The sky quickly darkens, the temperature drops, birds cease twittering and animals begin going to sleep. The gathered observers, whether or not from your individual group or from distant international locations, are united within the expertise.

An addictive passion

There are two warnings related to total solar eclipses. One is that chasing them is addictive. Typically individuals who have seen their first eclipse instantly wish to begin planning to see their second.

I can vouch for this personally—after watching my first total eclipse on December 4, 2002, from the Woomera Rocket Vary, I grew to become most eager to look at one other. Seeing the corona surrounding the darkish sun come into sight was an awe-inspiring expertise, heightened by the fascinating location and the elation of fellow observers. My subsequent eclipse was on August 1, 2008, at an much more fascinating location—a seashore on the shore of the Novosibirsk Reservoir in Siberia; and most not too long ago, I watched the Far North Queensland eclipse on November 14, 2012.

The opposite warning is that this: the one time it is secure to look immediately on the sun is in the course of the transient interval of totality. All different occasions, in the course of the partial phases earlier than and after, it’s essential to take precautions.

For this, particular eclipse glasses can be found from planetariums, public observatories, newbie astronomy teams and astronomy shops. Simply ensure that the glasses have the CE European commonplace mark.

Taking pictures is secure, although solely throughout totality until you might have the suitable filters. A tripod is crucial, because the corona is faint and you have to lengthy exposures. Seasoned eclipse observers arrive at eclipse websites loaded with professional-grade cameras and telephoto lenses. But when it is your first time, it is in all probability higher to simply watch and take in the occasion, fairly than strive photographing it.

Plan forward and keep cell

After this week’s eclipse in Australia, the subsequent total solar eclipse shall be seen on April 8, 2024, from the US and Mexico. After passing via Mexico, the path of totality sweeps throughout the US from Texas to Maine, earlier than transferring to elements of Canada.

There are a lot of potential viewing spots alongside the trail. Nonetheless, earlier than selecting a website, it is essential to check the “climate report” for the eclipse. This grants one of the best likelihood of avoiding the eclipse watcher’s best enemy—clouds.

Nonetheless, even with one of the best advance planning, last-minute clouds are potential. Seasoned observers attempt to keep cell, in order that if the weather forecast is dangerous for his or her location, they will transfer to a different location to keep away from the clouds.

The US total solar eclipse shall be adopted on August 12, 2026, with one the place the path of totality passes over Spain and Iceland. Then there shall be one on August 2, 2027, seen from Egypt and Saudi Arabia.

An upcoming eclipse of best curiosity to Australians is the total solar eclipse on July 22, 2028, for which the trail of totality passes from WA via the Northern Territory to New South Wales cities comparable to Bourke, Dubbo and Mudgee earlier than reaching Sydney. It’s uncommon for a significant metropolis to be within the path of totality, and the five million individuals of Sydney will get a once-in-a-lifetime alternative to view a total solar eclipse from their houses or backyards.

After all, like at every other eclipse, clouds are a chance, so maintain a lookout for climate stories nearer to the date. Earlier than eclipse day, take a look at the forecasts from the Bureau of Meteorology and specialized astronomy websites.

As talked about, for severe eclipse observers, mobility earlier than a total eclipse is crucial. For instance, on the November 14, 2012, eclipse in Far North Queensland, a Sydney Observatory group made a profitable final minute dash inland to keep away from the forecast poor climate.

Clouds, nevertheless, usually are not all dangerous. For a similar eclipse, I used to be at Palm Cove Beach and happily, the clouds parted simply initially of totality. The thrill concerned made for a improbable and distinctive expertise.

If you’re not at North West Cape this week and wish to expertise the wonders of a future total solar eclipse, it’s possible you’ll wish to begin planning now.
