In Hinduism, a lunar eclipse, also known as Chandra Grahan, is considered an inauspicious event caused by the shadow planet Rahu, who is believed to disrupt the moon's positive energy. This period is regarded as a time of heightened spiritual significance, during which devotees observe rituals such as fasting, abstaining from food and water, performing prayers, and chanting mantras to cleanse negative energies.

This year (lunar eclipse), Chandra Grahan will be observed from September 7 to 8, 2025.

A lunar eclipse occurs when the Earth is directly between the Sun and the Moon, casting its shadow on the lunar surface. The moon appears red due to a phenomenon called Rayleigh scattering (the same effect that colours sunsets). As sunlight passes through Earth's atmosphere, shorter blue wavelengths scatter, leaving longer red and orange wavelengths to illuminate the moon.

Eclipse will begin from 9:58 PM on September 7 and will end at 1:26 AM on September 8.

The entire event will last approximately 3 hours and 28 minutes, with totality spanning 82 minutes. Each phase of the eclipse will be observed simultaneously by viewers across regions where the moon is visible.

Tip 1: Unlike solar eclipses, lunar eclipses are completely safe to observe with the naked eye. However, to see the additional details, you can use binoculars or telescopes as well.

Tip 2: To pick the right spot, choose a spot with a clear, open sky and minimal light pollution, such as rooftops, backyards, balconies, scenic lookouts, or near monuments.

Tip 3: The solar eclipse will last for 82 minutes, from 11:00 PM to 12:22 AM, but the full eclipse spans from 8:58 PM to 1:26 AM. It is recommended to stay awake for the entire event.

Tip 4: For photography, you can use a tripod and manual camera settings to capture the moon's red-orange visuals.
