They don't actually say it in the article but IC 342 is slightly bigger
than the full moon (but a lot dimmer). Not confusable with a new comet
so it isn't a Messier object (although it is bright enough to be one).
https://en.wikipedia.org/wiki/IC_342
It is in the Caldwell catalogue by Patrick Moore (slightly controversial)

https://en.wikipedia.org/wiki/Caldwell_catalogueNice overview
I found I can use right mouse in Firefox browser and take a screenshot of the Wikipedia list, then select 'whole page'
Gets the whole list.
I won't display in Firefox as you would expect, but to display it I can use 'dillo' web browser on Raspberry,
and then you can scroll over the page again.
I use that method for sheet music now, and last nigh displayed it with my Iconnect laser projector.. 2 meters wide :-)
Resolution of that laser projector is shit (very low), but to project stars and stuff its likely OK.
Will have a go when it is dark, brightness is not much from that thing either , OK on an A4 format paper.
Playing!
I was looking for the northern light here, but too much clouds and rain somebody a bit more south here photographed this November 6: https://zoom.nl/foto/landschap/3633939/noorderlicht-friesland
It seems the sun's intensity is now so much higher that the northern light can be seen all the way to the south where I live.
It is maybe? related to the global-warming we observe,
as well as the disappearance of clouds on Neptune: https://edition.cnn.com/2023/08/22/world/neptune-disappearing-clouds-solar-cycle-sun-scn/index.html
So all that CO2 babble has little to do with warming I think, just a new sales tactic.

A telescope that uses light seems to be a breakthrough.

I glimpsed it on Monday night but missed the really juicy bit :( I have
seen stronger but not of a couple of decades. We are at solar maximum
now which has turned out to be rather stronger than anyone expected.
It was seen by people only a few miles from me. I just wasn't looking at
the right time. It was only very bright here for a couple of hours.

NB humble mobile phone will record it in colour even when the eye sees
only monochrome. It has to be quite strong before you see colour naked
eye. I have never seen it that bright...
It seems the sun's intensity is now so much higher that the northern light can be seen all the way to the south where I live.

Not at all. AGW deniers were predicting that the sunspots would vanish >completely this cycle. Here is an example from the Daily Wail in 2018.

Whilst sunspots and solar activity do make a small difference it is
mainly in fluffing up the Earth's atmosphere (bad for low orbit
satellites) and a tiny increase in intensity. Sunspots are obvious dark
spots but are accompanied by much larger brighter areas called faculae
so there is a net increase in solar output when there are lots of
sunspots ~0.1%.
It pales into insignificance when compared to the Earth's eccentricity
which makes about 7% difference annually between perihelion and
aphelion. It makes a huge difference whether being closest to the sun >coincides with northern or southern hemisphere summer (and also how
eccentric the Earth's orbit is which also varies very slowly).

Yes. Milancovitch cycles: https://old.world-mysteries.com/alignments/mpl_al3b.htm
But there is all sorts of radiation coming from the sun, not so much dark spot related we do not know much about.
Neither do we know much about the processes inside the sun and the variation of those over time. IR radiation, other wavelength...
CO2 babble is mostly sales related.
:-)
Kids fall for it.
It is a bit like witch hunts were in medieval times.
