A total lunar eclipse took place on Saturday, September 16, 1978, the second of two total lunar eclipses in 1978. The Moon was plunged into darkness for 1 hour, 18 minutes and 39 seconds, in a deep total eclipse which saw the Moon 32.683% of its diameter inside the Earth's umbral shadow. The visual effect of this depends on the state of the Earth's atmosphere, but the Moon may have been stained a deep red colour. The partial eclipse lasted for 3 hours, 27 minutes and 11.6 seconds in total. [1]

Overall, it will be the third largest and darkest lunar eclipse of the 21st century. While it will have similar values to the lunar eclipse of July 16, 2000, totality will not last over 106 minutes due to the moon's relatively large apparent size as seen from Earth and greater speed in its elliptical orbit. Totality's expected to last 100 minutes 34 seconds from 9:11:39 to 10:52:15 with the greatest point at 10:01:57 UTC.

A total lunar eclipse will occur on Wednesday, June 9, 2123, with maximum eclipse at 05:06 UTC. A dramatic total eclipse lasting 106 minutes and 6 seconds will plunge the full Moon into deep darkness, as it passes right through the centre of the Earth's umbral shadow. While the visual effect of a total eclipse is variable, the Moon may be stained a deep orange or red colour at maximum eclipse. This will be a great spectacle for everyone who sees it. The partial eclipse will last for 3 hours and 56 minutes in total. The penumbral eclipse lasts for 6 hours and 14 minutes. Maximum eclipse is at 05:06:28 UT. This will be the longest Total Lunar Eclipse since 16 July 2000, and the longest one until 12 May 2264 and 27 July 3107, though the eclipse on June 19, 2141 will be nearly identical in all aspects. This will also be the longest of the 22nd century and the second longest of the 3rd millennium. The eclipse on June 19, 2141 will be the second longest of the 22nd century and the third longest of the third millennium.
