Hinode Mission to Capture Annular Solar Eclipse This Weekend

On May 20-21, 2012 an annular eclipse of the Sun will be visible from within a narrow corridor along Earth’s northern Hemisphere — beginning in eastern Asia, crossing the North Pacific Ocean, and ending in the western United States. A partial eclipse will be visible from a much larger region covering East Asia, North Pacific, North America and Greenland.

The joint JAXA/NASA Hinode mission will observe the eclipse and provide images and movies that will be available on the NASA website at Due to Hinode’s orbit around the Earth, Hinode will actually observe 4 separate partial eclipses.” Scientists often use an eclipse to help calibrate the instruments on the telescope by focusing in on the edge of the moon as it crosses the sun and measuring how sharp it appears in the images. An added bonus: Hinode’s X-ray Telescope will be able to provide images of the peaks and valleys of the lunar surface.
