Solar Sketch August 27, 2011
This morning I observed the sun and made a sketch of several of the numbered active regions facing the earth. The atmosphere was not great as I had to make the sketch early (7:30-7:55 MST) and the image at the eyepiece was not as steady as I would have liked. Typically, the best window to observe the sun is right around 2 to 3 hours after sunrise. In addition, the transparency was average due, I think, to high levels of humidity.
Below left is my sketch of the sun at 1455 UT, and Below right is an image from the solar observatory at Mauna Loa, Hawaii, part of the National Solar Observatory. The Mauna Loa image is from about 4 hours following my observation.
