!['@[512633402082535:274:Melvin Nicholson Photography] spotted this stunning example of a fog bow on Rannoch Moor yesterday.
What is a fog bow? The elements that make up a fogbow are the same as for a rainbow - sunlight at the observers back, and water droplets in front. The water droplets that make up fog are so tiny compared to raindrops, between 10 and 1000 times smaller, that while the light still reflects from the water droplet back towards the observer, the process of diffraction of the light by the droplet becomes a dominant effect.
The process of diffraction broadens the reflected beam of light which smears out the colours which give the characteristic ghostly white, or very faintly coloured fogbow. This also makes the fogbow much broader than a rainbow.
The fog bank has to be relatively diffused and thin to allow the light to pass through the droplets and create the effect. Fogbows are large, almost as big as rainbows
A similar effect can also be seen from aircraft in cloud droplets, when they're known as cloud bows.'](https://scontent.xx.fbcdn.net/v/t1.0-0/p235x350/15202764_10154281580879209_7623108251983078131_n.png?oh=69958794405b31e1cf7cfe6796e31e62&oe=58B31027)

Could we see snow?
Showers will turn increasingly wintry with #snow falling over the hills and mountains of Scotland, Northern Ireland and Northern England.
...Some of the snow may even reach lower levels across the far north and west of Scotland on Thursday.

The #jetstream will move southwards across the UK this week, bringing some wet and windy weather for a time, and also colder conditions
It's the biggest #supermoon (also known as #BeaverMoon) in nearly 70 years tomorrow night!
Why is it called a beaver moon? In the Northern Hemisphere November’s full moon occurs at the time of year when hunters used to set traps before waters froze over, to ensure a supply of warm furs for winter – hence the name ‘Beaver Moon’. This year, the Beaver Moon will also be a supermoon.
Lest we forget. We will remember them on #ArmisticeDay.
