Partial Solar Eclipse 2025 Date, Time: The last solar eclipse of the year will take place on September 21, 2025, just a day before the September equinox. While this Surya Grahan will not be visible in India, skywatchers in parts of the Southern Hemisphere — including Antarctica, New Zealand, and several Pacific islands — will witness the phenomenon.
A solar eclipse occurs when the Moon passes between the Earth and the Sun, partially or completely blocking sunlight from reaching Earth. Depending on the alignment, eclipses can be total, partial, or annular.
In a partial solar eclipse, only a portion of the Sun is obscured by the Moon, creating a striking celestial display. Unlike a total solar eclipse, the Sun is never fully covered, but the crescent-shaped views make it equally fascinating for observers.
The partial solar eclipse 2025 will be visible in:
Antarctica – where up to 86 per cent of the Sun will be obscured.
Southern New Zealand – coinciding with sunrise, producing dramatic crescent-shaped dawns.
Pacific Islands – varying levels of obscuration, including 32 per cent in Tonga, 27 per cent in Fiji, 23 per cent in the Cook Islands, and 17 per cent in Samoa.
For India and South Asia, the eclipse will occur overnight and will not be visible directly. However, astronomy enthusiasts can watch it through online live streams.
Eclipse begins: 10:59 pm, September 21, 2025
Maximum eclipse: 1:11 am, September 22, 2025
Eclipse ends: 3:23 am, September 22, 2025
The timing of the event, just before the September equinox, makes it significant. The equinox marks the start of spring in the Southern Hemisphere and autumn in the Northern Hemisphere, adding a seasonal connection to this rare astronomical highlight.
Skywatchers can look forward to a series of future eclipses: The first eclipse of 2026 will be an annular solar eclipse on February 17, 2026, visible from Africa, South America, the Pacific, Atlantic, and Indian Oceans, and Antarctica. Later, a total solar eclipse on August 12, 2026, will be visible to observers in Greenland, Iceland, Russia, Portugal, and Spain — the first such event in mainland Europe since 1999. In 2027, an annular solar eclipse on February 6 will be seen from Africa, South America, and Antarctica, followed by a total solar eclipse on August 2, 2027, which will also be visible from parts of India.
