Equinox day
March 20, 2008
Sometime today the equinox occurs. The Astronomy Picture of the Day site provides a spectacular view of the event, courtesy of the Expedition 15 crew. Earth dwellers will experience nearly 12 hours of daylight and 12 hours of darkness. Recorded last June from the International Space Station, the Sun’s limb still peeks above the distant horizon as seen from Earth orbit. Clouds appear in silhouette as the sunlight is reddened by dust in the dense lower atmosphere. Molecules in the more tenuous upper atmosphere are preferentially scattering blue light.
Dave, quite content with a vicarious viewing.

Got something to say?
That is simply an amazing and affecting photo! I’m also content with a vicarious view, a bit of a compensation for the tax expenditures which make such photography possible.
