According to NASA, the next total lunar eclipse will be on January 31, 2018, and will be seen in Asia, Australia and North America. Penumbral lunar eclipses will occur on March 23, 2016, September 16, 2016, and February 11, 2017. Penumbral eclipses are more difficult to observe because only part of the moon is eclipsed.
The celestial event will last about four hours and is the fourth and final eclipse of 2016. The next four penumbral eclipses will occur on Feb. 10-11, 2017; Jan. 10-11, 2020; June 5-6, 2020; and July 4-5, 2020. This is the last harvest moon eclipse until 2024. The next total eclipse of the moon will be Jan. 31, 2018.
