23rd August 2021 Observations & sketch
I have no computer and the Sun came out for the first time in a month, so I used my eyeballs instead
Time was 15:00-15:30 UTC (16:00-16:30 BST). I used the PST double-stack to initially sketch the surface. I really struggled to get the plage correct on a white page and so it took at least 4 attempts before I was kind of happy but I am certainly no artist. Filaments were easy to place as were the proms, however, they did change shape between the full disc view and the larger versions so they were a little different.
Seeing started settled but went very wobbly as the Sun past over the neighbour's house towards the end of the session. I am not very good at descriptions so here is the sketches instead. I thoroughly enjoyed myself, I should do this more often (the sketch, not a broken computer). Also, good job I have a work laptop with Photoshop on it

Wow, you're not bad at using a pencil. Lovely sketches, you inspired me to try.

Re: 23rd August 2021 Observations & sketch
WoW, Alexandra! These are awesome sketches. I started observing just over 30 minutes after you did so my view was probably quite similar. I noticed the bright plage of AR12859 had a rough cross or bird shape and that shows well in your sketch of it. The NW prom with the southward trailing tendrils also appeared to me quite similar to your sketch of it.
See, the old MK-1 eyeball can work quite well!! And so does your Coronado PST DS!!
I will post my observations shortly.

Re: 23rd August 2021 Observations & sketch
A super-superb sketch Alexandra.
So who needs an imaging computer now ?
James mention the "Mk-1 eyeball" - I hope to have two good ones - when the virus is less (or preferably none).
Very well done and thanks for the effort and sharing.

Re: 23rd August 2021 Observations & sketch
And at a cursory glance, AR12859 reminded me of a five-pointed star, and of the correct shape (mind games ), I even shuddered and refocused. Of course, there was no correct star, but the initial effect was unexpected and powerful.

Re: 23rd August 2021 Observations & sketch
Thanks guys for all the wonderful comments, I think everyone should at least try sketching once it would be nice to have some solar art as SPOD
On the plus side, whilst I was sketching Mr Dell engineer turned up again and this time replaced the motherboard (again) and the drive. He said to not let it update the Dell bios this time, however, it still did it automatically before we could stop it, but this time survived it!! So we have tentatively started to rebuild it. So perhaps by the end of the weekend it might be working again.

Re: 23rd August 2021 Observations & sketch
I've never tried sketching what I see, I'll have to do that at some point. Good sketches too! I wonder if you felt like Galileo as you drew them, same as he sketched the moon:)

Re: 23rd August 2021 Observations & sketch
That's real good sketching Alexandra, your post reminds me of when I used to sketch the moon in pre camera days with a 60mm Achromat on a non tracking AZ mount that I still have . then I would match my sketches with my moon atlas.

Congratulations on your artistic skills and remarkable patience!
Dare one suggest a harder pencil to avoid solar "black holes" due to "overdoing the contrast?"
[Only joking. Honestly!]

We are discovering another one of your talents, Alexandra: your sketches are super ! Good astronomers have patience and observation skills. You have both.

Re: 23rd August 2021 Observations & sketch
Great sketches ALexandra! It is nice to do visual and take it all in, although I don't sketch myself. Sun has been hiding this past week for us, or been out when we were moving between places. That's rather annoying about the lappy, very badly behaved of Dell.

Re: 23rd August 2021 Observations & sketch
I’ve been ‘behind the curve’ on Solarchat this week with travelling to and from Switzerland on business.
Anyhow, great sketches, Alexandra. I think the act of drawing brings a new dimension to solar work. It requires a deeper look at what we’re seeing so that the details can be transcribed onto paper. I’m a rubbish sketch artist, but promised myself some time ago (when I saw historical sketches at the Solar Exhibition at the London Science Museum) that I should have a go.
Maybe we should set up a solar sketch challenge
