Solar Art Exhibition in Hawaii

Sacred Space Astronomy avatarPosted on September 20, 2019 by Deirdre KelleghanSeptember 20, 2019

                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 →

Sun Pillar – Sun Drawing Ireland

Sacred Space Astronomy avatarPosted on May 25, 2018 by Deirdre KelleghanMay 27, 2018

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 →

A Slice of Solar Drawing in h-alpha

Sacred Space Astronomy avatarPosted on May 17, 2017 by Deirdre KelleghanFebruary 20, 2018
This entry is part 11 of 12 in the series Exploring the Solar System

On my 50th birthday my better half gave me a present of a PST 40 (Personal Solar Telescope) with a 40 mm objective. This gift was literally a piece of visual heaven. Since I acquired this fabulous instrument my work with it has always been drawing. Drawing the sun or even drawing features on the sun is without a doubt the biggest challenge in astronomical drawing. Here is the thing, the telescope objective is just 40 mm, the sun as I see it is only about 30 mm of that 40mm to the eye. Using an 8 mm eyepiece gives about a 50X magnification and therefore the best view of the features and action on the disc and on the limb. There is no point whatsoever in drawing something at a diameter of 30 mm unless you provide your viewers with magnifying glasses or the object is a daisy. Therefore I work mostly at dinner plate size, sometimes at side … Continue reading →

Misinformative Books from Surprising Places

Sacred Space Astronomy avatarPosted on March 6, 2021 by Christopher M. GraneyFebruary 22, 2021

Misinformation.  It is a big topic these days, and a big problem.  And when the topic is astronomy and the Copernican Revolution, misinformation abounds, even in the relatively durable, more controlled medium of books.  “Caveat lector!” applies to this topic—“Let the reader beware!” Two recently-published books are especially disappointing in … Continue reading…

This entry is part 185 of 185 in the series In the Sky This Week

This week, the Moon appears in the predawn sky, Mars is in a close conjunction with the Pleiades star cluster, and the planets Mercury, Jupiter and Saturn appear low above the horizon before dawn; Mercury and Jupiter appear in a very close conjunction – less than 1 degree apart, as they swap positions over the course of several days.

A Sinus condition

This entry is part 42 of 42 in the series Lunarcy

North and east of the great crater Theophilus (diam. 104km) is Sinus Asperitatis (“Bay of roughness”) that opens towards Mare Tranquilitatis to the north. Right in the middle of the sinus is the pear-shaped crater Torricelli (roughly 20x30km) sitting off center in the ruins of an ancient unnamed crater about … Continue reading…

  • Joel Hopko March 6, 2021 at 11:54 am on Misinformative Books from Surprising PlacesProfessor Graney -- Ironic but perhaps understandable that the painstaking technical work of centuries should be reduced to a melodramatic contest of intrenched religious bigots bent on obscuring the truth versus "enlightened" clear seeing individuals heroically battling the establishment. After all, melodrama consistent outsells even the best technical literature. Still...
