When to See the Blood Moon in Somerset

Blood will be visible for five hours in the UK on January 21 and will be visible over most of North America, South America and parts of west and north Europe.

A Greenwich Observatory spokesperson said, “Those in the UK will be able to see every part of the eclipse as long as they are willing to stay up all night. The moon will start to enter the Earth’s shadow just after 2.30am GMT and the maximum eclipse will occur just before 5.15am. The entire eclipse lasts for more than five hours, ending at 7.48am.”

2018 witnessed two blood moons, the super blue blood eclipse on January 13 and a second total lunar eclipse on July 27.

The refraction of sunlight through the Earth’s atmosphere during a total lunar eclipse causes a blood moon to happen. The moon sometimes turns a deep copper colour. The level of dust in the Earth’s atmosphere will determine the colour of the moon; this is according to the Greenwich Observatory. Dust blocks out higher frequency blue light waves and allows the longer wavelength of red light to come through.
