A total lunar eclipse took place on Thursday, September 6, 1979, the second of two lunar eclipses in 1979. A shallow total eclipse saw the Moon in relative darkness for 44 minutes and 24.7 seconds. The Moon was 9.358% of its diameter into the Earth's umbral shadow, and should have been significantly darkened. The partial eclipse lasted for 3 hours, 11 minutes and 54.1 seconds in total.[1]

This event followed the annular solar eclipse of August 22, 1979.
