Solar Eclipse On September 21: Will It Be Visible In India?
This solar event occurs just before the September equinox, making it a unique chance to witness how Earth’s tilt and rotation influence the Sun’s apparent path in the sky
A breathtaking celestial event is on the horizon this September. On 21 September 2025, a partial solar eclipse, also known as Surya Grahan in India, will grace the skies, primarily visible across the Southern Hemisphere. Unlike a total solar eclipse where the Sun is completely hidden, this partial eclipse will showcase a striking crescent-shaped Sun as the Moon slides between Earth and the Sun, obscuring only part of its glowing disk.
What makes the September 2025 Solar Eclipse special?
This solar event occurs just before the September equinox, making it a unique chance to witness how Earth’s tilt and rotation influence the Sun’s apparent path in the sky. Scientists and sky-watchers alike will be able to study:
-Orbital mechanics – the predictable dance of celestial bodies.
-Shadow geometry – the difference between umbra (total shadow) and penumbra (partial shadow).
-Atmospheric effects – how light and sky color change during the eclipse.
It is not only a spectacular sight but also a textbook example of penumbral shadow formation, where the Moon blocks sunlight partially instead of completely.
