A 'Blood Moon Total Lunar Eclipse', a 'Super Moon' and a 'Blue Moon' will be visible to Sri Lanka on Wednesday.

For the first time since 1866, three lunar events will coincide on the same day; a 'Blood Moon Total Lunar Eclipse', a 'Super Moon' and a 'Blue Moon' will be visible to us on the 31st of January 2018, at moonrise in the eastern horizon, after 6.15pm. The eclipse begins at 4.21pm and will end at 9.38pm. The eclipse in total can be seen after 6.22pm with the moon entering completely into the umbra of the Earth. The eclipse reaches its maximum at 6.59pm.
When two full moons fall on the same month, the second full moon is called the 'Blue Moon'. This is just a name and the moon does not appear blue in colour.
When a Full Moon takes place, while the Moon is near its closest orbit to Earth, it is called a 'Super moon'. As a result, the moon appears 14 percent bigger and 30 percent brighter.
A Micro moon, on the other hand, is when a Full or a New Moon is at its farthest point from Earth. It’s also known as a Minimoon, and in this year the smallest full moon is due on the 27th of July. There will a total lunar eclipse on that day too.
A total lunar eclipse is sometimes called a 'Blood Moon', because of the reddish colour the Full Moon takes on, when fully eclipsed. As the Sun’s rays pass through the earth’s atmosphere, some colours in the light spectrum are filtered out, due to scattering. Red wavelengths are least affected by this effect, so the light reaching the Moon’s surface has a 'reddish hue'. This caused the fully eclipsed Moon to take on a red colour.

This eclipse is visible to many countries in Asia, Australia, the Pacific and North America.
