When 3 Norths collide - one for mapping geeks

A small village has made map reading history and become the first place where true, magnetic and grid north have met at a single point.
According to the Ordnance Survey (OS) the historic triple alignment made landfall in Langton Matravers, near Swanage in Dorset, on Wednesday.
It will stay converged for three and a half years as it travels through the UK.
OS spokesman Mark Greaves said it was not related to climate change.
Records held by the OS, Britain's national mapping service, date back to the 1930s but Mr Greaves said this was the "first time ever in British mapping history" the three norths had aligned.
"Magnetic north has a habit of wandering around, but this is unusual, it's not been in this orientation for hundreds of years," he added.

Is there a separate WGS84 north or does that line up with True North?

Always knew that true north was in the south

Lines of longitude pass through true north

Ok all you Southern luvvies,welcome to being a Northerner,sadly it will not last for long.Very soon you will notice a physical difference.You arms will get shorter and your pockets get deeper,you will find it hard to get your wallet out.You may start taking differently,tha knows,ebygum.Not to worry it won't last long,you could even start calling your wife our lass.But the important thing is take care of the whippet.The flat cap is not compulsory but you are in luck,here in CycleChat land we have our own Northern fashion guru by the name of Accy.Who is already setting up an emergency online help forum for advice on waistcoats,hobnail boots and corduroy trousers.So look forward to an exciting few months.

I think there MAY have been some misunderstanding here ...

Anyway, fear not, things will return to normal in a couple of years (they say):

According to the OS, the converged line will pass through nearby Poole by Christmas, before moving reaching Hebden Bridge in Yorkshire in August 2024.

It will leave the English coast at Berwick-Upon-Tweed in August 2025.

It does not hit land again until roughly May 2026 at Drums. Its last stop in Scotland, and the UK landmass, is Fraserburgh around July 2026.

Face it true north, magnetic, and grid north are in the south now and you will not get them back for some time unless you pay the ransom. You can keep the polar bears that roam your streets.

2024 being the 50th Anniversary year of West Yorkshire, and Hebden Bridge being the last town wholly within the West Riding.

T'is a sign...

This is badly worded by the BBC article. All it mean is that the direction of the 3 norths are exactly the same if you are stood in wherever in Dorset this morning, nit that you would really notice. The point where this occurs over time will draw a line / arc through the UK over the next 3 years.

At least it's heading north.

 

[Hover Fly]

True and grid norths are unchanging, there is one line through the country where they align and it will never change (2 deg. W of Greenich. Magnetic north is constantly changing, hence those panels on OS maps showing how to calculate It for the current year,

It's grim up Langton Matravers....
