On May 10, 1994,
a spectacular annular (ring)
eclipse of the sun was visible
from the southwestern regions of
North America all the way to the
northeastern U.S. and Canada.
This photo blends 18 separate
images to show the eclipse as it
progressed at 4-minute intervals
against the crystal blue sky
over La Catedral de la Asuncion
in Hermosillo, Sonora, Mexico.
