Rising Prominence

Prominence - April 10, 2010
Prominence – April 10, 2010
Sketch and Details by Les Cowley

For at least three days April 8-10, 2010 a large and ever-changing prominence rotated into view over the Sun’s NE limb. Its extent in solar longitude must therefore be considerable. Here is its appearance 09:00 UT on 10th April. Sketched directly at the eyepiece of a Solarmax 60 single stacked H-alpha scope 50 – 80X. Daler Watercolour, Studio and Drawing pencils on black Camford paper.
