Blood Moon over West Norfolk tonight

Look out for a red moon tonight - a partial lunar eclipse could be visible from West Norfolk along with the rest of the UK.

The eclipse coincides with the 50th anniversary of the Apollo 11 launch, which took the first men to the moon.

The lunar eclipse should be most visible at around 10.30pm.

What is a partial lunar eclipse and why does it happen?

A lunar eclipse is when the sun, earth and a full moon are almost exactly in line, with the earth in the middle, casting a shadow on the moon's surface.

The moon dims dramatically but usually remains visible.

During a partial eclipse, some - but not all - of the moon passes through the darkest area of the Earth's shadow.

The surface often appears red because the earth blocks direct sunlight from reaching the moon and so the only light reflected off the surface has been refracted by the earth's atmosphere.

Like a sunset or sunrise, this scattering of blue light gives the moon a red appearance.

So, the moon may be rusty red tonight, or a less exciting dark grey - depending on conditions.

The moon travels to a similar position every month at full moon, but the tilt of the lunar orbit means it normally passes above or below the terrestrial shadow and no eclipse takes place

Where can I see the Blood Moon in West Norfolk?

The Blood moon can be seen best from rural areas at 10.30pm, preferably from a location where the horizon is clearly visible.
