took place at the Moon's descending node of the orbit on Wednesday, February 10, 1971, the first of two total lunar eclipses in 1971. It had an umbral magnitude of 1.30819. The moon passed through the center of the Earth's shadow. The Moon was plunged into darkness for 1 hour, 22 minutes and 11.4 seconds, in a deep total eclipse which saw the Moon 30.819% 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, 44 minutes and 42.9 seconds and in total.
