Surprises on the Turkish Mediterranian

Eclipse 

Eclipse

The total solar eclipse seen from the Turkish Mediterranean coast last year
was our first eclipse. It was an overwhelming and unforgettable experience.
We wanted to soak up the spectacle and so deliberately did not take a
camera, our only equipment was binoculars for a quick look at prominences
and the corona immediately after the start of totality.

All the textbook sights were there, Venus and Mercury before totality, the
pink prominences, a gauzy corona pearly white and twisted and pulled by the
sun’s magnetic fields, diamond rings whiter than diamonds and the receding
lunar shadow blotting out distant mountains. That much was expected. But the
overpowering impressions were the ones that were not expected. The point
like sun and greying light before totality like being in a steel tank lit by
a single light bulb. The rapid and wholly shocking plunge downwards in light
as totality started. The swiftly changing and blazing diamond rings, the
sheer speed of it all. For the first time we got the real sense that we were
on a turning Earth with the Moon and Sun shifting and moving in the heavens.

This little acrylic on board painting tries to sum up those impressions. It
fails miserably – but then what could succeed when pitted against a real
solar eclipse!

Radiant spectacle

The Sun with Sunspot groups 484,486, and 488

Today, March 2, 2007, the sunspot number is zero.

The sunspot number on October 28, 2003 was 238. An X-17 solar flare erupted that morning. Sunspot groups 484,486, and 488 were associated with Coronal Mass Ejections and auraural activity. The attached watercolor was based upon a white-light solar image captured with a 4″ refracting telescope, a white-light-solar filter, and a digital camera. The image of the sun with sunspots 484, 486, and 488 was processed in Photoshop and then printed. In a photocoping machine a transparancy was made. The transparancy was placed on an overhead projector and the projected image was traced and colored with watercolor pencils. Then, with a brush, water was added to the sunspots and to the remaining surface and background.

If the use of an “overhead projector” sounds like something from a school project, it was. Students at the A.R. Gould School in South Portland, Maine have used this process numerous times to document their observations.

… just a thought about tracing. In the late ’90s, I sent a cardboard-box camera obscura to Betty Edwards, the author of “Drawing on the Right Side of the Brain”. In her book she recommends that one should try to copy an image that is upside down; she suggests that that may allow the observer/drawer to see what is there and not what one expects to be there. In the camera obscura that I constructed, the image was projected upside down. In our conversations I asked her about the whether she thought tracing was drawing. She said that if two people were to trace the same thing that the finished drawings would be different, because drawing is about how we see things. (She also said that tracing allowed muscles to build muscle memory. I suppose that that is similar to practicing scales in music.)
