The Sun Over Nagykanizsa

Hi!

The data of drawing: 07.Jun.2011.
Telescope : Colorado PST.
Observing Location: Nagykanizsa – Hungary, Canis Maior Sun Observatory
(www.nae.hu)

Today I’ve made a h-alpha sketch through with Colorado PST H-Alpha
telescope. The drawing is made between 8:00 an 10:00 UT from
Nagykanizsa Canis Maior Sun Observatory , using a red pastel pencil on
black paper.

The weather was bad. The sky was cloudy. Sun only 1-3 happened upon lawsuits up.
I was not able to finish a drawing. The clouds did not allow it. I
managed to prepare a digital scheme it redrawing.

This digital drawing preparated GIMP 2.6 programs, based on a pastel sketch.

Thank you for it!

Clear Sky !

Transit of Venus from the Temple of Apollo

Hey Artists!

It is now One year left to the last transit of Venus across the sun for this time!
It happens on the “wrong side” of the earth for us in Norway, but in northern Norway
we can see it low over horizon in the night (midnightsun).
I enjoyed the transit in 2004 in Greece. Info on my sketch! I used crayons and pencil.

Best wishes for this on “the other side”!!

Western Prominence

2011 06 01, 1500 UT – 1630 UT
Solar h-alpha, prominences

PCW Memorial Observatory, Ohio USA – Erika Rix, www.pcwobservatory.com
Temp: 32.3°C, Humidity 42%, SE winds 5mph
Seeing: Wilson 4, Transparency: 2/6

DS 60mm Maxscope, LXD75, 21-7mm Zhumell

Sketch created scopeside with black Strathmore Artagain paper, white Conte’ crayon and pencil, Derwent charcoal pencil, black oil pencil

There were six active regions on the Sun, but a western prominence region caught my eye as a possible CME that took place during my observation. If it was simply an erupting prominence, it was the brightest I’ve witnessed as such. I’ve created an animation of my sketch sequence that I recorded during the observation at 5-minute intervals.

Total Eclipse in Malindi

Hey artists!

This is my first and only total eclipse of the sun. It is only > one thing to say, beautiful, and this is still
my finest minutes as an amateurastronomer!
The eclipse started with a long lasting diamondring, and ended > with a shorter one.
Info on my sketch!

Best wishes and clear sky from Per-Jonny Bremseth

The sky was clear today, so i aimed my new solartelescope at the Sun to see some Solar Flares. There where pretty much of those flares visible today. As you can see on the sketch, three huge flares where visible on the leftcorner of the sun.
Our Sun reaches the Solar Maximum in 2013, so it will become more and more active. This is the time to buy a solartelescope!

– Weather: hot and dry
– Seeing: (very) bad
– Telescope: Coronado P.S.T.

I’m ready for the Solar Maximum!

New Active Region

DS 60mm Maxscope, LXD75, 21-7mm Zhumell, ETX70 AT w/tilt plate and white light glass filter.

All sketches done scopeside and flipped in Photoshop to match standard orientation. H-alpha sketch created with black Strathmore Artagain paper, white Conte’ crayon and pencil, Derwent charcoal pencil, black oil pencil. White light sketch created on photocopy paper with 0.5mm mechanical pencil and #2 pencil.

Transparency made it nearly impossible to view prominences at the start of the session with the thin layer of cirrus creating a milky white sky. There were small breaks that allowed me to sketch in some of the detail on a western prominence, that later as the transparency improved, showed an abundance of thin whispy structure that wasn’t captured on paper. By that time, I was already working on a full disk sketch in h-alpha. Seeing was terrific until I started on the white light observation, but had I set up the ETX at the beginning of the session to let the scope adjust to the warmth, it would have been much better by the time I observed with it. As it was, I observed in the observatory for protection of the wind as I view with a shade attached to the objective and wanted to avoid vibration.

There is a possible new active region between 1209 and 1208 that, while observing in white light, had several little spots forming an elliptical shape with pointed ends like a football. I noticed facula around 1208, but the seeing was so bad that I couldn’t make out a definite shape. The umbra of the preceding spot in that region was displaced, as was the preceding spot in 1203. I didn’t notice any sunspots in 1209 during my observation, but that may have been the result of the seeing.

The band of active regions is still putting on a nice show in h-alpha with more-defined plage around them.

The Active Sun

– Media: white pastel, black paper, PhotoShop CS5
– Telescope: Coronado P.S.T.

Today was a nice clear day in Holland. The sun was shining bright, so i aimed my brand new solar telescope (Coronado P.S.T.) at it to see some Solar Flares. There where many flares visible, and also some sunspots and other details on the surface.
This is my first solar sketch in H-Alpha. The original sketch is black & white, and i changed that colour in PhotoShop.

Clear Skies!

Our Star Revealed

2011 05 05, 1230 UT – 1515 UT
Solar h-alpha, NOAAs 11203, 11204, 11205, 11207 and prominences

PCW Memorial Observatory, Zanesville, Ohio USA – Erika Rix, www.pcwobservatory.com
Temp: 22.5°C, Humidity 38%
Seeing: Wilson 4, Transparency: 3/6

DS 60mm Maxscope, LXD75, 21-7mm Zhumell, ETX70 AT w/tilt plate and white light glass filter.

H-alpha sketch created scopeside with black Strathmore Artagain paper, white Conte’ crayon and pencil, Derwent charcoal pencil, black oil pencil. White light sketch created on photocopy paper with 0.5mm mechanical pencil and #2 pencil.

The Sun was a little too low in the observatory for me to stay inside at the beginning of the session, so I pulled all my gear onto the grass. It was probably the best move anyway, since it warmed up quite a bit during the session.

I started off with the Maxscope for an overall view. The prominence at the western limb caught my eye initially, but it was the prominence on the eastern limb that really put on a show. It was nearly three times taller than the other and had the faintest wisps of filament reaching out connecting the brightest three areas of that prominence section.

The h-alpha full disk was filled with filaments and plage within the band of active regions. I’ve flipped the views of both the white light and h-alpha full disk sketches to match the standard view (at least a little more so as I didn’t rotate it completely) for comparisons with SOHO views. In white light, there were three distinct areas of faculae, one each on the western and eastern limbs and one around AR 11207. I couldn’t detect 1205 in white light and although the Sun had rotated slightly, I’m fairly sure 1207 is indeed that designation in my sketch and not 1205. Prenumbrae were noted around the preceding spots in 1204 and around the entirety of 1203.
