Lokks good, Dee--lots of swirling action. Nice to have a target on the Sun to sketch, yes?

Beautiful sketch! :bow: :bow: :bow:

You've inspired me to take a look through my h-alpha solar telescope (as soon as the clouds clear.)

Thanks for sharing this image with us,

Mark

Dee, absolutely lovely sketch of this fascinating AR! :bow: :jump: :bow: The swirling turmoil is so elegantly captured. Your use of pastels and Conte' are so beautifully applied, very painterly.

Dee,

An impressive observation of an active region on the Sun. The region appears to come alive in your rendering. Thank you for sharing it with us all.

Thanks Jeffrey

The sketch is approx 7 inches by 7 inches centered on an A 3 sheet of black paper.

I observed the shape of the active region , the position of the sunspots , the plages, and any other disturbances that had defined shapes different to the rest of the solar disc close to the AR.

This is done by grating soft pastel to a fine powder and rubbing it by hand on the page in layers to build up as close to the grainy h alpha view that I see in my PST.

I tune in the scope to see only the sunspots and draw them into the image. They re tune the scope to see the active region in as fine a focus in the sweet spot that I can manage.

Then I draw in the bright areas and give more color to the extra bright plages. I use a lighter pastel draw the area surrounding the sunspots themselves.

I use fine grated graphite to depict the fibrils or mottles , ie the areas that seem to radiate out in loops from the AR.
They only exist for 10 or 15 mins but make shapes to my eye like loops and V's and appear to be made up of millions of dots and dashes. The grey area in my sketch represents the dots and dashes, fibrils/ mottles . I am working towards being able to draw this detail in a finer way so experiments like this sketch are the way to move that on.

Thank you for your interest , hope my description is of some use to you.

Dee
