WHAT'S NEW Robert L. Park Friday, 6 Jan 06 Washington, DC DEEP SPACE CLIMATE OBSERVATORY KILLED. http://bobpark.physics.umd.edu/index.html -------------------- "After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853 |

Nice image, but something must be off with the colors- the shadow looks brown but should be neutrally colored, as the moon will block all wavelengths equally.

John There's a lot of discussion upthread of DSCOVR images from the 2017 eclipse. The colors produced by the way they combine the data from different wavelengths makes a difference from what the human eye would see. Even the GOES visible wavelength photos showed a very dark area along the path when the Sun wasn't totally eclipsed at any point in this annular eclipse. |
