While the recent solar eclipse was unfortunately invisible across Bangladesh and much of South Asia, stargazers now have another celestial treat: a total lunar eclipse. Although brief, this phenomenon will be observable from Bangladesh, offering enthusiasts a rare chance to witness a “blood moon” with the naked eye.
What Causes a Lunar Eclipse?
Unlike the Sun, the Moon has no light of its own. It reflects sunlight, which is why it shines brightly in the night sky. A lunar eclipse occurs when the Earth passes between the Sun and the Moon, casting its shadow on the lunar surface.
During a total lunar eclipse, the Moon can appear deep red, earning it the dramatic nickname “Blood Moon.” Unlike a solar eclipse, which cannot be safely viewed without special eyewear, a lunar eclipse can be observed directly with the naked eye. Lunar eclipses also last much longer, allowing plenty of time for observation.
When and Where Will It Be Visible?
On 3 March, regions of the Earth experiencing nighttime will witness the lunar eclipse. Observers in Bangladesh and India will be able to see it, though only for a limited period.
The entire eclipse will span approximately five hours, with the most dramatic total phase lasting 58 minutes and 15 seconds. The eclipse will not be visible from every location on Earth; for instance, parts of western United States will see it from 4:04 AM to 5:02 AM (local time) on 3 March.
The timing for India and Bangladesh is as follows:
| Phase of Eclipse | India (IST) | Bangladesh (BST) |
|---|---|---|
| Total eclipse begins | 16:58 | 17:28 |
| Total eclipse ends | 17:32 | 18:02 |
| Partial eclipse ends | 19:53 | 20:23 |
Observers should look to the night sky during these hours to experience the Moon gradually changing colour as it moves through Earth’s shadow.
Why Does the Moon Turn Red?
During totality, the Moon is never completely black. Instead, it adopts a reddish hue due to Earth’s atmosphere filtering sunlight. As sunlight passes through the atmosphere, shorter wavelengths (blue light) scatter in all directions, while longer wavelengths (red light) are refracted and fall on the Moon’s surface. This selective scattering is why the eclipsed Moon glows dark red rather than disappearing completely.
For skywatchers in Bangladesh, the evening of 3 March promises a spectacular visual treat. With clear skies, anyone can witness the Moon slowly slipping into the shadow of the Earth and emerging as a glowing red orb—a perfect opportunity for photographers and astronomy enthusiasts alike.
