Comparison of two total lunar eclipses in 2022. At left is the total lunar eclipse of 16th May, captured near the Andes Mountains in Chile. The eclipse occurred a day before perigee (when the Moon is closest to the Earth) so it was larger in the sky than the eclipse in November. It also appeared darker compared to total lunar eclipses in the past few years due to volcanic ash from the Hunga Tonga-Hunga Ha'apai eruption in the previous January. At right is the 8th November eclipse, captured from Kitt Peak National Observatory, Arizona, USA. It occurred when the Moon passed through the northern part of the Earth's shadow where the effect of the ozone layer is more visible, showing as a turquoise tint on the northern part of the lunar disc.
