Chandra Grahan visibility in India and worldwide
The total lunar eclipse will be visible across India, including Delhi, Mumbai, Kolkata, Bengaluru, Hyderabad, Ahmedabad, Jaipur, and Lucknow.
Globally, it can be seen from most of Asia, Australia, Eastern Africa, and parts of Europe. However, it will not be visible in most regions of North and South America.
Why does the Moon turn red during Chandra Grahan?
During a total lunar eclipse, the Moon enters the Earth’s shadow. Instead of going completely dark, it appears reddish because sunlight bends through the Earth’s atmosphere and scatters, leaving only the red hues to reach the Moon. This is why the event is often called a “Blood Moon.”
Religious and cultural significance
In Hindu tradition, Chandra Grahan is considered a powerful yet inauspicious time. Rituals include:
- Avoiding food and water during Sutak.
- Chanting mantras and meditating during the eclipse.
- Taking a holy bath after the eclipse ends.
- Donating food and essentials to the needy.
It is also said that children, elderly, and ill individuals are allowed relaxed Sutak rules, as reflected in today’s timings.
What Chennai skywatchers can expect tonight
If skies remain clear, residents of Chennai will witness the Moon gradually darkening from 9 PM, turning deep red by 11:42 PM at maximum eclipse. The spectacle will last past midnight before ending around 1:26 AM.
