Spots AR2171 and AR2172 Solar

Active regions AR 2171 and AR 2172 - September 27, 2014
Active regions AR 2171 and AR 2172 – September 27, 2014

Hello,

As soon as I put the eye in the ocular of the glasses, my heart skipped a beat(I saw red)! That the Solar surface is magnificently stained!

I decide to crunch(outline) one of the spots (who(which) I ignore N at the time of the drawing), the 2172, telling me that the task is already very sufficient(self-important) seen the scale of details.

Once ended, of small spots in small spots, I decide shyly to widen the frame(executive) in 2171.

The twilights of the main spots appear finely chiselled on their outlines when the turbulence calms down in a regular way.

Finally, at the end of 2 big hours of observation stuck on the ocular, and the aching loins, all the spots situated downward the Solar surface is there! I thought not at all of arriving there at this stage(stadium) from the first moments.

Lunette 102 / 1000 – ocular E.S. 6,7 mm – prism Herschel + filter Continuum

Whrite 12 at 14 h UT – 27/09/2014

– France, department Yvelines
– Drawing makes for the criterium HB
– 2 working hours behind the ocular to realize the drawing.

First International Sun-Day
· Object Name (International public event)
· Object Type (Sun)
· Location (Varages – Provence France)
· Date (2014 June 22)
· Media (graphite pencil for the sun, water ink and watercolour for the scenery, white paper, Paint.Net to assemble)

This first International sun-day was a good time to show the sun to the public, today in the north hemisphere the day is much longer than the night. The day before, the local radio broadcast make our promotion. With the local association “AAP” (Association – Astronomie – Provence) of Varages we had good time and very nice public. Despite the fact that the sun was quite calm, we can show a very tiny archipelago of sun-spots on the middle of the disk as well as some spots neat the limb. Anyway, the proms make our day; they are much more attractive for the public today.
To sketch the H-alpha part of the sun (here the portion out of the disk) I used a Coronado 60mm refractor with a focal length of 1000mm ; for the inner portion, the disk in Wight Light, I used my 102mm refractor, same focal length with glass objective filter.

My place for looking at the sun
My place for looking at the sun

Since I exchanged Belgium for Sweden last year, I am faced with lack of astronomical darkness since mid april. Astronomical darkness (sun below 18 degrees of horizon) will only return end of august. Therefore I will be concentrating drawing more suns and moons instead of deepsky. The positive side to this is that in Winter time it ‘s astronomical dark at 5.30PM already 🙂

I have used my 21 years old TeleVue 101 SDF apochromate refractor, teamed with an (also old) Daystar 0.7Å h-alfa filter. A Barlow is needed to reach the required f/30 focal length. I am using a TeleVue alt-az Gibraltar mount.

I have added a picture to show the observation location. I have reached SQM 21.6 a number of times already.
Hope you like it.

best regards

Sun – White Light – February 4, 2014

Object : Star / Sun
Date : February 04, 2014
Time : 10:30LST / 03:30 UT
Location : Surprise Arizona USA
Medium : Digital sketch done on Iphone with apps
Instruments : Orion 25×100 Binos, William Optics GTF81 APO, 5mm Orion edge-on planetary eyepiece, White light filter, Iphone with PaintFX and Juxtaposer Apps.
Magnitude : -26.7
Weather : 65deg. F, Clear sky (in the morning), no wind and just great day altogether!

Comments: Greetings everyone! Please allow me to bring you this new digital sketch utilizing my Iphone. recently or should I say last month- January. The Sun presented us with one of the biggest sunspots in recent times. That sunspot being AR 1944, It crossed the entire disc of the Sun from our point of view and went all around to reappear again. Well, here I’ve done my best to depict it as it is already under way racing across the face of the Sun. It is now designated AR 1967. It also comes with a fairly huge companion group – AR 1968. As some of you may already know, these freckles on the Sun are ‘cold’ areas comprised of strong magnetic fields capable of hurtling solar flares or coronal mass ejections, CME’s for short. As an added reference, I superimposed an image of the Earth just for size comparison next to those massive sunspots.
Back to the sketch! Are digital sketches or drawings considered a genuine art medium? A medium for sure but I once thought that maybe it’s a bit like cheating. Textures, colors, filters and a plethora of other effects are already predetermined and laid out for you. I’d say, If you get to show and display the view or scene that you have in mind using a digital format and you succeed, then it’s all worth it. I like the the ‘old school’ pad and pencils but i had to give it a try. Enjoy!

Dark and Clear skies,

Juanchin

Hi

This is a sketch of the biggest sunspot I´ve ever seen. It´s so amazing that can be drawn with small telescopes like the one I´ve used: the Astro-Professional ED80 equiped with binoviewer, a pair of 19 mm eyepieces and a 2.6x galsspath, that gives a magnification of 78x. I have used a Baader solar film to observe the sun with security. Although the seeing was not good at all, the view was great and unforgettable.

Best regards.

AR1575

H-Alpha / White Light Sun - September 22, 2012
H-Alpha / White Light Sun – September 22, 2012

Object Name Sun
Object Type Sunspot 1575 and crown
Location Néoules Provence France
Date 22 sept. 2012 – 13h TU
Media (graphite pencil for the spot, red pastel for the crown, two different white papers, Paint.net)

I made two separate sketches, one in H alpha via a classic PST for the crown, the second one through a 1000/102 refractor with solar continuum filter for the spot.
I used several eyepeaces.
The compilation was done with the freeware software : Paint.Net
Conditions were perfect, the sun was hot here… !

Clear sky to you all
