Only a few hours are left for the September 21 partial solar eclipse. Excited skygazers await the celestial phenomenon, which is the last solar eclipse of this year.
A solar eclipse occurs when the Moon passes directly between the Earth and the Sun. Depending on alignment, eclipses may be total, annular, hybrid, or partial.
During the September 2025 solar eclipse, the Moon’s shadow will not fully cover the Sun. Observers in the penumbra—the lighter part of the shadow—will see the Sun appearing as if a “bite” has been taken out of it, creating the partial eclipse effect.
The eclipse will not be visible in India as it takes place after sunset, when it is already dark.
The partial solar eclipse is scheduled for September 21. In some locations, up to 85% of the Sun’s disk will be covered by the Moon.
Start: 10:59 PM IST, September 21
Maximum: 1:11 AM IST, September 22
End: 3:23 AM IST, September 22
For India, the Sun will have already set, making the eclipse invisible to observers across the country.
The next solar eclipse visible from India will occur on 2 August 2027, when most of the country will witness a partial solar eclipse in the late afternoon and early evening.
The September 2025 eclipse will be best seen in the Southern Hemisphere. Skywatchers in eastern Australia, New Zealand, Antarctica, and the Pacific islands will enjoy the spectacle.
Antarctica will offer the most dramatic views, with much of the Sun obscured by the Moon’s shadow. Vast stretches of the Pacific Ocean will also experience partial coverage, giving island communities a rare glimpse.
Countries in Asia, Africa, Europe, and the Americas, including India, will completely miss this solar phenomenon.
To watch the September solar eclipse, it is important to have proper eye protection—solar eclipse glasses or eclipse goggles.
They are not the same as regular glasses that use a solar filter to protect eyes during a solar eclipse. These glasses must be worn while watching the eclipse.
However, eclipse enthusiasts can take off these glasses for a very short window during the period of totality, when the Moon completely obscures the Sun.
