Sarah had marked April 8, 2024, on her calendar for months. She drove six hours from Dallas to a small town in Arkansas, joining thousands of others who’d made the pilgrimage. When the moment came, she watched through her eclipse glasses as the moon slowly crept across the sun’s face. The temperature dropped ten degrees in minutes. Street lights flickered on. And then, for just over four minutes, day became night.
“I’ve never experienced anything like it,” she told her sister later, voice still shaking with excitement. “Four minutes felt like both an eternity and a heartbeat. I can’t imagine what seven minutes would feel like.”
Well, Sarah won’t have to imagine much longer. Astronomers have just announced the official date for something truly extraordinary.
The Longest Solar Eclipse of Our Century Has Its Official Date
Mark your calendars for June 25, 2132. That’s when the longest solar eclipse of the 21st century will plunge parts of the world into darkness for an unprecedented seven minutes and twenty-eight seconds.

This isn’t just another eclipse. While most total solar eclipses last between two to four minutes, this upcoming event will stretch nearly twice as long as anything we’ve seen in our lifetimes. The last eclipse to exceed seven minutes occurred in 1973, and after 2132, we won’t see another one this long until 2186.
“The duration of a solar eclipse depends on several perfectly aligned factors,” explains Dr. Michael Chen, an astronomer at the National Observatory. “On June 25, 2132, the moon will be at its closest approach to Earth, the sun will be at its farthest point, and observers will be positioned at just the right latitude. It’s celestial choreography at its finest.”
The longest solar eclipse will cast its shadow across parts of the Atlantic Ocean, West Africa, and the Mediterranean region. Cities like Casablanca, Morocco, and parts of Spain and Portugal will experience the full duration of totality.
What Makes This Solar Eclipse So Special
Several rare astronomical conditions must align perfectly to create such an extended period of totality:
- Moon’s proximity: The moon will be near its closest point to Earth (perigee), making it appear larger in the sky
- Sun’s distance: Earth will be near its farthest point from the sun (aphelion), making the sun appear slightly smaller
- Geographic positioning: The shadow will cross areas where Earth’s curvature maximizes totality duration
- Orbital mechanics: The moon’s shadow will move relatively slowly across Earth’s surface
Here’s how this eclipse compares to other significant ones:
| Date | Location | Duration | Notable Features |
|---|---|---|---|
| July 22, 2009 | China, Pacific Ocean | 6 minutes 39 seconds | Current century record holder |
| April 8, 2024 | North America | 4 minutes 28 seconds | Most recent major eclipse |
| June 25, 2132 | Atlantic, West Africa | 7 minutes 28 seconds | Longest of 21st century |
| May 5, 2186 | South America, Atlantic | 7 minutes 29 seconds | Next ultra-long eclipse |
“What people don’t realize is how different a seven-minute eclipse feels compared to a three or four-minute one,” notes Dr. Elena Rodriguez, who has witnessed twelve total solar eclipses. “At four minutes, you’re still processing what’s happening. At seven minutes, you actually have time to observe the corona’s structure, notice how animals behave, and truly absorb the experience.”
Planning for the Ultimate Celestial Show
While 2132 might seem impossibly far away, eclipse chasers are already making plans. The path of totality will be approximately 160 miles wide at its maximum, giving millions of people the opportunity to witness this once-in-a-lifetime event.
Prime viewing locations will likely include:
- Morocco: Casablanca and Rabat will experience nearly full totality
- Spain: Southern regions including Seville and Córdoba
- Portugal: Lisbon and surrounding areas
- Atlantic Ocean: Cruise ships and specially positioned vessels
The eclipse will begin its journey across the Atlantic Ocean around 14:42 GMT, with maximum eclipse occurring at approximately 16:15 GMT. Unlike some eclipses that favor remote locations, this one will pass over several major metropolitan areas.
“The beauty of the 2132 eclipse is its accessibility,” says Dr. Rodriguez. “You won’t need to travel to the middle of the Pacific or the Antarctic. Major cities with excellent infrastructure will be right in the path.”
Why Seven Minutes Changes Everything
Those extra few minutes might not sound like much, but they transform the entire eclipse experience. During shorter eclipses, observers often report feeling rushed, trying to take in everything at once. With seven minutes of totality, people will have time to truly observe phenomena that usually flash by too quickly to appreciate.
The extended duration will allow observers to:
- Watch the sun’s corona change shape as solar wind patterns shift
- Observe planets and bright stars visible during totality
- Notice detailed animal behavior changes
- Experience multiple waves of temperature drops
- Capture detailed photographs without feeling rushed
“During the 2009 eclipse in China, I remember thinking how quickly it was over,” recalls amateur astronomer James Peterson. “People were crying, not just from emotion, but from frustration that they couldn’t absorb it all. Seven minutes would be transformative.”
Scientists are already planning research projects to take advantage of the extended totality. The longer duration will allow for more detailed studies of the solar corona, space weather effects, and even how ecosystems respond to prolonged darkness.
Weather considerations will be crucial for the longest solar eclipse. June in the Mediterranean and West Africa typically offers clear skies, but climate patterns could shift over the next century. Eclipse chasers are already studying historical weather data for the region to identify the most promising viewing spots.
FAQs
How often do solar eclipses lasting over seven minutes occur?
Extremely rarely. The last one was in 1973, and after 2132, the next won’t occur until 2186. These ultra-long eclipses happen only a few times per century.
Will the 2132 eclipse be visible from North America?
No, the path of totality will cross the Atlantic Ocean, West Africa, and parts of southern Europe. North America will not see totality for this particular eclipse.
Why can astronomers predict eclipses so far in advance?
Solar and lunar orbital mechanics are extremely precise and predictable. Astronomers can calculate eclipse paths centuries in advance using established mathematical models of planetary motion.
What’s the difference between a partial and total solar eclipse?
During a partial eclipse, the moon only covers part of the sun. A total eclipse occurs when the moon completely blocks the sun’s bright surface, revealing the corona and creating the dramatic day-to-night effect.
Is it safe to look at a solar eclipse?
Only during the brief period of totality when the sun is completely blocked. At all other times, including partial phases, you need proper eclipse safety glasses to avoid permanent eye damage.
How wide will the path of totality be in 2132?
The path will be approximately 160 miles wide at its maximum, significantly wider than many eclipses. This means more people will have access to the full totality experience without traveling to the exact centerline.
