Century’s longest lunar eclipse

Sunday، 29 July 2018 - 02:41 PM

The longest lunar eclipse to occur so far in the 21st century took place on Friday 27/7/2018 and lasted for more than six hours, and Cairo was one of the prime locations to clearly see this rare "blood moon" phenomenon.

The phenomenon started at about 6 pm, and totality took place at about 9 pm and lasted for about 1 hour and 47 minutes. Totality is when the moon is fully under Earth's shadow.
A total lunar eclipse occurs when the Earth's position is between the moon and the sun in a straight line. The Earth's atmosphere refracts light from the sun onto the moon's surface, resulting in the orange-red colour and creating the so-called "blood moon."

The entire six-hour phenomenon was visible by the naked eye.
