Total Lunar Eclipse Today: Time & Visibility in India
A rare celestial event, a total lunar eclipse, is unfolding today, March 3, 2026, and will be visible across much of India. The eclipse began at 3:20 PM IST and is expected to conclude at 6:47 PM IST, offering skywatchers a captivating spectacle as the Moon passes through Earth’s shadow. This event marks the first Chandra Grahan – as lunar eclipses are known locally – of the year, coinciding with the vibrant celebrations of Holi in some regions.
Understanding Lunar Eclipses: Umbral and Penumbral Shadows
Lunar eclipses occur when the Earth positions itself between the Sun and the Moon, casting a shadow on the lunar surface. The India Meteorological Department (IMD) explains that there are two primary types of lunar eclipses: total and partial. A total lunar eclipse happens when the entire Moon moves into the Earth’s umbral shadow – the darkest part of the shadow. Conversely, a partial lunar eclipse occurs when only a portion of the Moon enters the umbral shadow. Today’s event is a total lunar eclipse, meaning the entire Moon will be enveloped in darkness. A less dramatic phenomenon, a penumbral lunar eclipse, occurs when the Moon passes through the Earth’s penumbral shadow – the outer, lighter part – and is often difficult to notice.
Visibility Across India and Beyond
Although the eclipse began at 3:20 PM IST, the visibility will vary depending on location within India. Most observers across the country will witness the eclipse ending around the time of moonrise. However, those in North-East India and the Andaman and Nicobar Islands are in a particularly favorable position to observe more of the totality phase before it concludes. Beyond India, the eclipse will also be visible from Eastern Asia, Australia, and the Americas, making it a globally observable event. You can find more details on regional visibility from the Economic Times report.
The Science Behind the “Blood Moon”
Total lunar eclipses are often referred to as “Blood Moons” due to the reddish hue the Moon takes on during totality. This coloration isn’t caused by the Moon itself changing color, but rather by the way Earth’s atmosphere filters sunlight. As sunlight passes through the Earth’s atmosphere, shorter wavelengths of light (blues and greens) are scattered away, while longer wavelengths (reds and oranges) are refracted, or bent, towards the Moon. This refracted light is what gives the Moon its characteristic reddish glow during a total lunar eclipse. The Business Today article details this phenomenon, noting that this particular eclipse is expected to be a “deep” one, meaning the Moon will travel fully into Earth’s darkest shadow, intensifying the reddish glow.
Detailed Timeline of the Eclipse (IST)
The IMD has provided a detailed timeline for the eclipse, allowing skywatchers to plan their observations:
- Start of the eclipse: 3:20 PM
- Totality begins: 4:34 PM
- End of totality: 5:33 PM
- End of the entire eclipse cycle: 6:48 PM
It’s important to note that even if you aren’t able to see the beginning of the eclipse, the later stages, particularly the end of totality, will be visible as the Moon rises in the evening sky for many locations.
A Rare Coincidence: Eclipse and Holi
This lunar eclipse is particularly noteworthy as it coincides with the Hindu festival of Holi, celebrated with vibrant colors and joyous festivities. The occurrence of a lunar eclipse on Holi is a rare event, happening only once every hundred years. Traditionally, certain rituals and restrictions, known as the ‘Sutak period,’ are observed during a lunar eclipse in Hinduism. However, modern interpretations and practices vary widely. The NDTV report highlights this unique timing and the cultural significance of the event.
What Comes Next: Continued Observation and Data Analysis
Following the eclipse, astronomers and skywatchers will analyze the data collected during the event. This includes studying the composition of the Earth’s atmosphere based on the way it filters sunlight during the eclipse, as well as observing the behavior of the Moon’s surface under different lighting conditions. Further research may also focus on refining eclipse prediction models and improving our understanding of the complex interactions between the Sun, Earth, and Moon. The data gathered from this eclipse, and others, contributes to a broader understanding of celestial mechanics and the evolution of our solar system.
