March 1978 lunar eclipse

A total lunar eclipse took place on March 24, 1978, the first of two total lunar eclipses in 1978. The moon passed through the center of the Earth's shadow. The Moon was plunged into darkness for 1 hour, 30 minutes and 40.2 seconds, in a deep total eclipse which saw the Moon 45.179% 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, 38 minutes and 34.5 seconds in total.[1]

Tritos series

The tritos series repeats 31 days short of 11 years at alternating nodes. Sequential events have incremental Saros cycle indices.

This series produces 20 total eclipses between April 24, 1967 and August 11, 2185, only being partial on November 19, 2021.

Half-Saros cycle

A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros).[2] This lunar eclipse is related to two solar eclipses of Solar Saros 129.

March 18, 1969	March 29, 1987
