A rare Blue Moon is to appear in Scotland's skies this weekend.
It will be the first time in 70 years that the Blue Moon has coincided with Halloween, and will make for quite the show for skywatchers.
Scots should turn their eyes to the sky this afternoon (Saturday) at around 4.53pm - less than 20 minutes after the sun sets.
It isn't the first time we've seen a full moon this month, with the first being on October 1, and this owes itself to the moon's name.
The term 'Blue Moon' actually doesn't have anything to do with its colour.
The term used to refer to the third full moon within a month that featured four full moons.
However, back in 1946, an astronomer names James High Pruett referred to the second moon in a month as a Blue Moon in a magazine article - and although it remains to be a 'Blue Moon blooper', it is still widely used.
And the last time we had a Blue Moon was back in 2018, on March 31.
We won't get to see this again until August 22, 2021, so make sure to check the skies tonight.
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
