September 1978 lunar eclipse

A total lunar eclipse took place on 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]

Lunar year series

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 23 total eclipses between June 22, 1880 and August 9, 2120.
