A total lunar eclipse will occur on July 27, 2018. The Moon will pass through the centre of the Earth’s shadow. This will be the first central lunar eclipse since June 15, 2011.
People in Cornwall and Devon can first see the eclipse happening at approx 9pm on Friday July 27. The eclipse actually starts to happen before then – from 6.14pm – but the moon will be below the horizon so we won’t be able to see it until later.
The weather at the time of writing (23/07/18) shows Friday evening in Cornwall being clear with great visibility. https://www.metoffice.gov.uk/public/weather/forecast/f24b5jryz#?date=2018-07-27

Since it will occur near apogee, this eclipse will also be the longest total lunar eclipse in the 21st century. Totality will last approximately 103 minutes and be the second total lunar eclipse in 2018, after the one in January.
A lunar eclipse occurs when the Moon passes within Earth’s umbra (shadow). As the eclipse begins, Earth’s shadow first darkens the Moon slightly. Then, the shadow begins to “cover” part of the Moon, turning it a dark red-brown color (typically – the color can vary based on atmospheric conditions). The Moon appears to be reddish because of Rayleigh scattering (the same effect that causes sunsets to appear reddish) and the refraction of that light by Earth’s atmosphere into its umbra.
The following simulation shows the approximate appearance of the Moon passing through Earth’s shadow. The Moon’s brightness is exaggerated within the umbral shadow. The northern portion of the Moon was closest to the center of the shadow, making it darkest, and most red in appearance.
