Stargazers in the Southern Hemisphere are in for a rare treat this September. On the 21st, the last solar eclipse of 2025 will unfold just before the equinox. How will this celestial event appear across the region, and can it be seen safely?

Where Will the Eclipse Be Visible?

The partial solar eclipse will cover New Zealand, Antarctica and parts of the South Pacific. Observers in southern New Zealand and Antarctic research stations will see the moon cover much of the sun. For instance, Auckland will experience a 60% eclipse, while Christchurch sees 69%. Invercargill will witness up to 72%, and Wellington 66%. Will island nations get a good view? Tonga will observe a 32% eclipse, Fiji 27%, Cook Islands 23% and Samoa 17%.

In Antarctica, eclipse coverage varies widely. Marambio Base experiences just 5%, Mario Zucchelli Station sees 72%, and McMurdo Station 69%. Ross Ice Shelf will have about 65% eclipse, while the Antarctic Peninsula sees only 12% as the sun sets.

Timing and Safety Measures

When exactly does the September 21 eclipse begin? The eclipse is already in progress on sunrise in New Zealand, painting dramatic crescent dawns. Adequate eye protection is paramount, as direct viewing of the sun is never safe, even in partial phases. Certified solar eclipse glasses must be worn by all spectators.

Will the eclipse be visible in India? Unfortunately, India lies outside the eclipse path, so it will not be visible there. For those keen on timing, Space.com will livestream the event, offering global viewers a chance to follow this celestial spectacle safely.

Why September 2025 Solar Eclipse Matters

Why is this solar event unique? It occurs on the doorstep of the September equinox, when the sun crosses the celestial equator. This marks spring in the Southern Hemisphere and autumn in the north. Even though it is not a total eclipse, the moon will cover up to 86% of the sun, making it a deep partial eclipse. The September 21 solar eclipse is the last of the solar activities for 2025, and it presents breathtaking sights leading into year-end.

Whether viewing in person or on the internet, enthusiasts need to come prepared with cameras and safety gear. Solar eclipse photography guides and recommended astrophotography cameras can be found for safely and stylishly capturing the moment.
