Mark, I am on the Lancaster one and the Calsky one and I haven't had any alerts? mmmm

We'll have our settings different in the app. I'm on 'minor' & 'UK'.

On the little graphic of the suns disk it is the bright region at the 2 o'clock position.

or are the sunspots causing comets?

Nice capture Stu! I sympathise with the tree, i'd arranged with my neighbour that I getting her overgrown conifer cut down and disposed of, however at the last minute she bottled it on me and said no - grrrr! I shall persist.

Lovely prom shots and a nice setup too Eric!

Top shots Franco!

Thanks Alexandra!

I'm on the lancaster one on my phone (aurora watch UK)

It is a pair of external Lunt 50 etalons - a ls50c and a ls50fha.

Thanks everyone! I did a prom shot too. They looked great visually in single stack.

Hi All, There were some cloud breaks later in Sunday afternoon, and I was able to observe the sun through an open door way as it made it's way towards the horizon. It has been a while since i've got any solar in and it was nice to stand and observe visually for a while before snapping a quick full d...

Good record Stu, i'd a couple of alerts come through on my phone these past couple of days too. Your graphic also includes the cycle 25 sunspot that briefly appeared.

I think once we get into spring we will start seeing the return of the spots in the northern hemisphere again. Cycle 24 the northern hemisphere peaked a good year and half before the southern hemisphere peaked, so, would be reasonable to assume this asymmetry in the start of 25, and seeing spots in ...

It's definitely a cycle 25 spot. Take a look at the graph from Belgium, it's starting to uptick quite quickly once we get into the new year.

Super shots Marty! The spot is reversed polarity (compared to cycle 24 spots) so is part of cycle 25.

Good job there Marty!

That's a stunner Valery!

I think used in conjunction with another filter with a similar steep profile just below 400nm could work as a basic CaK filter.

A quiet sun but nice disks!

'Off the Shelf' UV achromats aren't ideal, but could form a starting point for such a scope. You could make a tiny full disk instrument; the 50/200 https://www.edmundoptics.eu/f/near-uv-nuv-achromatic-lenses/13900/ could replace the objective in a finder scope, and then mount the filters on the nose...

Could be an interesting one

A really nice run of images Brian!

Those are lovely shots Franco!
