Alaskans can catch a glimpse of a partial solar eclipse on Sundayafternoon. That s when the moon will pass in front of the Sun andcast a shadow across the home planet s surface on a trajectorythat begins in Asia and crosses the ocean into North America. Something strange is about to happen to the shadows beneath yourfeet, teases NASA s eclipse story with gobs of links and graphics, transforming sunbeams acrossthe Pacific side of Earth into fat crescents and thin rings oflight. The moon s penumbral shadow will darken most of Alaska during the event. In Anchorage, theeclipse will commence at one second past 3:17 p.m. Waterproof Infrared Camera

That stillheld true Saturday, though viewing may be sporadic through clouds. The narrow path of the more intense annular eclipse — where the moon appears directly in front of the Sun to blockabout 94 percent of its surface — will cross the Pacific Oceansouth of the Aleutian Chain. For observers in this zone, the sunmight appear as a dazzling ring around the darker body, hence thename, annular, which came from a Latin word meaning ring. While Anchorage and the rest of Alaska will see the eclipse withthe moon off-center from the sun, the full ring effect of theannular phase will be visible from Taiwan to Lubbock, Texas in anarc across the North Pacific south of Alaska, wrote Mike Dunham,in a particularly detailed eclipse advance posted by the Anchorage Daily News. The maximum coverage of thesun — hence the thinnest ring — will be seen just south ofuninhabited Amatignak Island in the Aleutians, about 125 milessouthwest of Adak and the southernmost point in Alaska.
