Solar Art Exhibition in Hawaii

Sacred Space Astronomy avatarPosted on by

                Exhibition in Hawaii Some time ago a painting of mine won a prize in the My Sun My Star Contest. This was a solar art competition involving photographs, drawings and paintings inspired by the sun. The contest was run by The National Solar Observatory in Boulder Colorado. One of the aspects of the prize is that my painting X-Ray Sun (above) will go on exhibition . On Friday September 20th if you are in Hawaii (how exotic) one of my paintings and in addition one of my solar drawings will be on show. Since the prize came my way I was asked if another work of mine could be included in their exhibitions. NSO requested one of my solar drawings. That sketch it is called East Limb Proms. The venue is The University of Hawaii – Institute for Astronomy, it is on the island of Maui. The event is an open day … Continue reading →

Experimental sketch goodbye – Active Region 2738

Sacred Space Astronomy avatarPosted on by

April 16th On April 16th Active Region 2738 was heading towards the limb, looking very dramatic. I decided to try an experimental sketch using just pencil to capture the action around the giant sunspot. I used a very black pencil called a Conte de Paris Carbone B, which was deeply black. For the sketch I also used some silicone tipped brushes, these were perfect for drawing with and allowed some good flexible movement to be developed.  There is always massive movement  in the area around sunspots. A kind of disturbance caused by the huge magnetic activity in the sunspot itself. The light bridge and umbra had changed since a previous observation on  April 10th. It was clearly visible in my h-alpha view  however the seeing was soft not as sharp as I would have liked. A well shape filament would have been nice to observe but none developed as I viewed. April 18th On April 18th another opportunity to view … Continue reading →

Drawing Active Region 2738

Sacred Space Astronomy avatarPosted on by

  Massive sunspot It was great to have a new huge active region to observe recently. This massive area of magnetic disturbance heaving its way across the solar disc was fascinating to watch. The weather smiled on Ireland, several days of sunshine in April is unusual to say the least. Active region 2738 boasted the largest sunspot in several years. Its diameter is three times that of the Earth. Across the center of the umbra is a light bridge circa  20,000 km long and circa 800 km wide. !! Drawing Active Region 2738 is a challenge indeed but it  is also an opportunity to try some new ideas. At 12:36 UT on the 10th of April,  a very bright plage flare erupted from the base of two dark filaments. Then one of the filaments got very long very quickly. Then the flare subsided. It’s the yellow part of the drawing. The umbra was very dark and the surrounding penumbra seemed … Continue reading →

Days of continental heat,water restrictions, dry ground , struggling plants and animals. Ironically despite the clear daytime skies the sun itself has been almost devoid of drama. My more recent focus of attention has turned to a new kid on the block. Comet –  C/2017 S3 (PanSTARRS) on its first visit to our solar system.  An icy comet oozing gasses from within itself as it heads toward the sun.  Perihelion is on August 15th, many think it will not survive past this … Continue reading →

Sun Pillar – Sun Drawing Ireland

Sacred Space Astronomy avatarPosted on by

We had a winter of record winds, freezing temperatures and darkness. However this week, it seems the summer has finally arrived in Ireland. On May 21st I noticed a developing sun pillar on the horizon. As it progressed I took several images, each equally beautiful.  The pillar of light  interacted with the sky and the sea, altering colour and bringing drama as it peaked and faded after sun set.  Beautiful to watch, it seemed to pierce the clouds just above the suns departure point.   Sun pillars are shafts of sunlight  glinting off ice crystals in our atmosphere. This phenomenon is explained well here on this wonderful site Atmospheric Optics    On May 23rd the sun offered an active region for drawing. OK now the atmosphere was not the steadiest I have ever seen, but it was hot and the sky was blue. The active region was small and complex, the challenge to draw the sun in h-alpha with my  … Continue reading →

Go Observe – The Terminator

Sacred Space Astronomy avatarPosted on by

When the phrase “The Terminator”  is mentioned in may conjour up  ominous dark tones lurking within its meaning.  A science fiction phrase where a cybernetic organism  can ask for  ‘your clothes, your boots, and your motorcycle’ then ride off to alter the course of humanity.  Or the visually rich line that demarks daytime on the moon’s surface from night-time on the moon’s surface. The terminator is far from a straight line, it is ragged and uniquely fluid. Sunlight illuminates unevenly as it fills craters.  Shadows form and transform during its progression across the lunar topography. Craters that penetrate the terminator and show their rims as glints of light in the blackness bring a tactile quality to a sketch.  Lunar sketching in the area of the terminator often brings up a dilemma . When a sketch takes several hours, sometimes the terminator vista alters to offer a new and brightly lit feature.  This crater or mountain only revealed as you finish. … Continue reading →

Watch Dancing Solar Proms

Sacred Space Astronomy avatarPosted on by

Below is a slide show of the original nine drawings of the proms on the solar limb on July 19th 2007 Proms It is truly fascinating to watch prominences on the solar limb. One day back in July 2007 the sun came out after many weeks of dullness. The eastern limb was graced with many twisting dancing proms. In order to capture the movement and continuing changes in the structure of the proms I decided to do a sequence of drawings.  In general  I would draw what I see and then wait 15 or 20 minutes before drawing the same proms again.  A slight haze developed, therefore the sketches have a little more time in-between them. The morning proms seemed to leap into space, with the exuberance of dancers in a ballet. In the afternoon the action continued, this time akin to bubbles interlinking and changing shape . Arcs of energy holding on to the limb.   Some proms seemed to … Continue reading →
