8 November 2022 Chandra Grahan Time: A Celestial Spectacle Over India
The eighth of November, 2022, marked a significant astronomical event for skywatchers across India—a total lunar eclipse, or Chandra Grahan. This celestial phenomenon, where the Earth positioned itself directly between the Sun and the Moon, cast our planet’s shadow upon the full lunar surface, creating a breathtaking copper-red hue. For millions, it was not merely a scientific event but a moment steeped in cultural and spiritual traditions, observed with both reverence and curiosity.
Precise Timing and Visibility Across India
The eclipse unfolded in distinct phases, with its visibility varying slightly depending on one’s location within the country. The partial eclipse, the first visible sign of the Earth’s shadow touching the Moon, commenced at approximately 2:39 PM IST. The grandeur of the total eclipse, however, began after moonrise. For most of India, the Moon rose already in the clutches of the eclipse. The maximum eclipse, the peak of the celestial alignment, occurred around 3:47 PM IST, while the total eclipse phase concluded by 4:49 PM IST. The final partial phase lingered until 5:52 PM IST. Consequently, observers in cities like Delhi, Kolkata, and Mumbai witnessed the Moon ascending in the eastern sky, already partially or totally eclipsed, presenting a dramatic and somewhat eerie spectacle.
Cultural Resonance and Traditional Practices
In India, a Chandra Grahan is deeply intertwined with mythology and religious customs. Many view it through the lens of the Samudra Manthan legend, where the demons Rahu and Ketu are said to occasionally swallow the Sun and Moon. This narrative fuels a variety of practices. It is common for people to refrain from cooking or eating during the eclipse, with many temples closing their doors to visitors. Pregnant women, in particular, are often advised to stay indoors to avoid any perceived negative influences. Following the eclipse, a period of purification is observed; people bathe, cleanse their homes, and partake in prayers and charity. These practices, passed down through generations, highlight the profound cultural significance of such natural events.
The Science Behind the Blood Moon
Scientifically, a total lunar eclipse is a harmless and predictable alignment. The captivating red colour that earned this event the nickname ‘Blood Moon’ is a result of Rayleigh scattering. As sunlight passes through the Earth’s atmosphere, the shorter blue wavelengths are scattered outward, while the longer red wavelengths are bent, or refracted, toward the Moon. It is this filtered red light that illuminates the lunar surface during totality, much like the glow of countless simultaneous sunrises and sunsets around the Earth’s rim being projected onto the Moon. Unlike a solar eclipse, a lunar eclipse is perfectly safe to view with the naked eye, allowing everyone to enjoy the show without any special equipment.
A Moment of Collective Wonder
The total lunar eclipse of November 8, 2022, served as a powerful reminder of our place in the cosmos. It bridged the gap between ancient tradition and modern understanding, uniting people in a shared experience of awe. Whether witnessed from a crowded metropolitan rooftop or a quiet village field, the slow, majestic dance of the Earth’s shadow across the Moon provided a moment of quiet reflection and universal beauty, a celestial clockwork that continues to inspire humanity.
