Will we see the rare Halloween full blue moon over West Berkshire?
More than 70 years since it last happened on October 31
The second full moon of October - and therefore a full blue moon - will appear tonight, Halloween, October 31.
A Halloween full moon doesn't happen very often - the last one was in 2001, and before that in 1955. The next Halloween full moon will be in 2039 - in fact there will only be six full moons on Halloween in the 21st century.
A blue moon is a rare phenomenon so for it to appear on the day of ghoulies and ghosties and long-leggedy beasties is an extra treat - conjuring images of howling wolves silhouetted against the moon.
It is more than 70 years since a full blue moon occurred on Halloween.
This full moon is also known as the Hunter's moon - so called by native Americans because it is the best season for hunting game - most especially deer, which were tracked in the autumn moonlight.
So fingers crossed the clouds don't get in the way and we can enjoy a spooktacular Halloween full blue moon.
