Sketch created scope-side with white card stock, felt-tipped black artist pen, #2 graphite pencil.
Faculae were present in several areas around the limb, particularly around ARs 1473, 1469, 1474, 1475 and north of 1473 ~45 degrees. Sunspots were observed in all five active regions with 1474 ad 1475 only showing one per region. Seeing was poor and it was windy. I had to wait several moments to catch sharp views so may have missed out on pores in those areas. There were a few sunspots in the two active regions near the western limb, 1473 and 1469.
Active region 1471 was the area I concentrated for today’s sketch. The larger sunspot grouping was in the eastern region of that AR with very defined edges to the penumbrae and radial structure reaching to the umbrae. It was painstaking to wait for the winds to drop and seeing to settle to grab as much detail as I could. I dropped magnification and then increased when sky conditions permitted. That group appeared to have a chain of smaller sunspots, all sporting both umbrae and penumbrae leading east from the larger cluster of sunspots. A very faint speckled area was a further few degrees beyond the chain. I couldn’t make out if they were pores or simply penumbral blotches.
Moving to the western area of the AR ~10-20 degrees showed three more small groupings in that active region. The middle two of the AR had both umbra and penumbra and faint areas that looked penumbral to the south of them. The furthest grouping to the west was too soft and faint to be sure of its structure.

The sun’s activity is very important in this moment, causing greats eruptions that I drew the best I could. Note that few sunspots appear (maximum 2). The dark lines on the sun are eruptions pointing in our direction.
Hi folks, I send you here my sketch made with Meade Lx200 ACF 12″ from Zelow Observatory in central Poland. Drawn at scope with graphite pencil and black pastel pencil on white paper, other info on the sketch:)
Location : Castres, south-west France (near Toulouse)
Date : from 22 to 31 august 2013
Media : graphite pencil, white paper
Dayly sketch of sun made through a small Coronado PST (H Alpha) + 15mm Televue eyepiece
1) dayly observing sun coronado around 12h TU
2) quick sketch with ballpen on paper notepad (2 minutes)
3) later copy out on drawing paper with graphite pencil (10 to 12 minutes)
4) picture take of each drawing with camera + Photoshop processing
– flipping horizontally and vertically in order to see the correct sun orientation
– grouping the 9 pictures + date on the same sheet
One may see the sun rotation from August 26 to 29 watching at spots.
I saw some material projections ejected into space (see August 30)
We currently have a great solar activity
To see the solar prominences evolution one should have to observe every hour !
Thank you for taking into consideration this small contribution

Hello to all,
Today we had a sunny morning, only the sky was crossed with light cirrus clouds. Why shouldn’t I look to the sun? The sun came up with some sunspot groups and an bright area (maybe flares?) on me. I could not help, I took the drawing pad an my pencil and start to draw. Maybe the sunspots in overview are little bigger than they real were, but I think the details outside the circle are located close to the original. Hope you like it too.
This is my drawing of the sun in white light at May 19, 2013.
Object name: Sun
Object type: Star
Location: Koudekerke, Netherlands
Date: May 19, 2013
Media: Graphite pencils and processed with GIMP
Time: Around 14:00 UT
Telescope: Sky-watcher refractor (102/500mm)
First I made a fussy grey background for the sun and drew a circle. Thereafter I drawed the sunspots and the rest of the details inside the disk. I scanned the picture and processed it with GIMP for a smooth contrast and brightness.
I send you hereby my sketch made this Saturday at Polaris Observatory, Hungary. I used a 114/900 Skywatcher with Baader solar filter for white light sketch and a Lunt 35 for the H-alpha sketch.
The most intersting part is a solar prominence on the northern edge, which is was a very 3D something, biting in the sun-disk.
Equipments used: 114/900 SW (100x) & Lunt 35/400 H-alpha
Date: 18th February 2012, UT: 10:40 (white light) and 11:20 (H-alpha)
Place: Hungary, Budapest, Polaris Observatory
