It is from AuroraWatch UK at Lancaster Uni :--  https://aurorawatch.lancs.ac.uk/

An impressive magnetogram along with it as well !

Pity it has dropped back to green now 😞

I've used AuroraWatchUK (the iOS app) for quite a few years now (I've still not seen any proper aurora myself yet though 🤫)

You can set alerts if it goes amber / red

And you can also access the Shetland webcams and keep an eye on whats happening up there (usually bad weather 😀)

All in all, a decent app.

I just noticed this had gone red by chance earlier by checking the Aurorawatch graph 

https://aurorawatch.lancs.ac.uk/

I've now installed the AuroraWatch UK app. 

And I have the Glendale Aurora app. 

We just need the clear sky and crescent moon app 🤔

Apparently there were some very rare pink aurora earlier this month, caused by ionized nitrogen at lower altitudes:

I wonder if there were more last night?

Nitrogen, not Neon.  The photos are still spectacular though. The nitrogen spectrum has a number of lines at the blue and red end but not in the green, which combine to produce the pink colour. This reference has a set of nice spectra and images showing the colours generated.

Fun fact:- blue and red without green also produces the  pink colour seen in reflected sunlight from the JWST sun shield as in my spectrum here

You're right. The article confused me as it referred to a "neon pink glow".

[Malpi12]

I may be indulging in wishfull thinking ! but -
 ACE (1hr uptream at L1) is reporting a large negative Bz, which is often a precursor to geo storms.
Worth keeping a monitor perhaps

Ah! AuroraWatch UK was green when  posed that.

Now RED

I use the glendale app on my phone (also available as a website - https://aurora-alerts.uk/). The person who runs it is based in Glendale on Skye, but it flags live reports from other users (along with photos) so you can get an idea of what is actually visible. In my case nothing, as it is wall-to-wall cloud here!

[Malpi12]

Hmmm.That didnt do much, just enough to turn my 50% clouds to 100% !
