The entire eclipse lasted more than three hours and caused the moon to turn coppery red as sunlight going through Earth’s atmosphere bounced off its surface. The moon captivated residents in Indian capital New Delhi, as sky gazers watched the event from India Gate war memorial.
The eclipse occurred during the rare occasion of a second full moon in a single month, otherwise known as a “blue moon,” and during a point in the moon’s orbit – its perigee – at which it has reached its closest position to Earth, thus making it appear larger and brighter in the sky than normal, as a “super moon.”
The reddish appearance of the lunar surface – the moon’s image does not vanish entirely during an eclipse – occurs when rays of sunlight passing through Earth’s atmosphere around the sunrises and sunsets on Earth’s edges from the moon’s perspective filter red light through to the moon.
The last time all three conditions occurred for a single lunar eclipse visible from North America was in 1866, according to the meteorological forecaster AccuWeather.
