Washington: A rare total lunar eclipse that involves the second full moon of the month – popularly referred to as a Blue Moon – is set to take place on 31 January for the first time in over 150 years. This will be the first eclipse of 2018.
For the Indian subcontinent, the Middle East and Eastern Europe, the eclipse will already be underway as the Moon rises.
The Pacific Ocean will be turned towards the Moon at the time and the eclipse will take place during the middle of the night. Central and eastern Asia, Indonesia, New Zealand and most of Australia will get a fine view of this Moon show in the evening sky. Alaska, Hawaii and northwestern Canada will see the eclipse from start to finish. Moonset will intervene for the rest of North and Central America, however.
The duration of the total phase is 77 minutes, with the moon tracking through the southern part of the Earth’s shadow.
During totality, the Moon’s lower limb will appear much brighter than the dark upper limb, ‘Space.com’ reported.
After this year, the next time that a Blue Moon passes through Earth’s umbra will be on 31 December 2028 and, after that, on 31 January 2037. Both of these eclipses will be total. Before 2017, there was 8% partial eclipse on 31 December 2009, but the last total eclipse of a Blue Moon happened all the way back in 31 March 1866.
