Partial Solar Eclipse on September 21-22: Everything You Need to Know

September 19, 2025 | 08:02 pm

TEMPO.CO, Jakarta - Another cosmic event will greet us just this week. The second and final solar eclipse of the year will grace the skies on September 21/22, bringing with it a stunning partial solar eclipse.

Skywatchers in the Southern Hemisphere will be in prime position to witness this celestial spectacle of the Moon appearing to take a "bite" out of the Sun.

Whether you're hoping to catch the partial eclipse at its best or are simply curious about this cosmic phenomenon, here’s everything you need to know before the big day of the partial solar eclipse this week.

What’s Unique About the September’s Solar Eclipse

While this September’s solar eclipse is only partial, People.com and Forbes emphasize the dramatic nature of the event. It’s estimated that up to 86% of the Sun will be hidden from view in some regions, making it unusually deep for a partial eclipse.

Adding to the spectacle, the eclipse will also appear at sunrise in certain locations, creating the possibility of a stunning visual effect as the rising sun is partially covered.

When Is September's Solar Eclipse?

The final solar eclipse of the year will take place on September 21, just one day before the September equinox. However, if you're in New Zealand, the partial eclipse will occur on the morning of September 22, visible just after sunrise.

Here’s a quick overview of the timing in UTC Time:

• First location sees eclipse begin: September 21, 17:29:43

• Maximum eclipse: September 21, 19:41:59

• Last location sees eclipse: September 21, 21:53:45

In Jakarta time (WIB), this corresponds to:

• First location sees eclipse begin: September 22, 00:29:43

• Maximum eclipse: September 22, 02:41:59

• Last location sees eclipse: September 22, 04:53:45

Where Will September's Solar Eclipse Be Visible?

As reported by Time and Date, September’s partial solar eclipse will be visible to around 16.6 million people, representing just 0.2% of the world’s population. Those with the best views will be in parts of New Zealand, the Pacific Islands, and Antarctica.

Meanwhile, the eclipse won’t be visible for skywatchers in the Northern Hemisphere, including North America, much of Asia, India, and South America.

Best Places to See the September’s Solar Eclipse

But when it comes to the best places to view September’s solar eclipse, a few remote spots truly stand out. Because this is a remote, southern eclipse, regions in far southern New Zealand, the Pacific Islands, including the Cook Islands, Fiji, and Norfolk Island, as well as parts of Antarctica, are in for the best treat. In these areas, viewers may witness up to 70% of the Sun obscured at the peak of the eclipse.

According to Forbes and Sky Night Magazine, the following are some of the best places to view September's solar eclipse.

Antarctica

• McMurdo Station

• Zucchelli Station

• Young Island, Ballenny Islands (remote Antarctic islands claimed by New Zealand)

How to See September's Solar Eclipse Safely?

It’s crucial to protect your eyes while observing the solar eclipse. Eclipse glasses must be worn at all times during the event to prevent serious eye damage. Be sure to purchase them from a reputable astronomical supplier to ensure safety.

Alternatively, you can use solar telescopes or sunoculars, which are designed specifically for safe solar viewing.
