阅读理解。 SAN FRANCISCO - In the western U.S., Hawaii and elsewhere across the globe, moon watchers were treated Saturday to a rare celestial phenomenon: a total lunar eclipse (月全食). For about 50 minutes starting at 6:06 a.m. PST, the moon was completely blocked by the Earth's shadow. With only some indirect sunlight able to reach it after passing through the Earth's atmosphere, the moon took on a reddish glow. Since the atmosphere scatters blue light, only red light strikes the moon, giving it a dark red color. Dally Sam, who runs a public relations firm in Hawaii, said it had been cloudy and rainy, but the weather cleared just in time for the eclipse. Around 3 a.m., he awoke, as he usually does, and remembered to step outside the house in time tocatch the eclipse about a half hour later. No one else in the neighborhood was up. "It was turning that dark red color," Sayre, 47, said, "I'd better grab a camera. To be able to see itjust right outside our house was really cool." At the local observatory in Los Angeles, some 300 people, many clutching coffee cups in the coldmorning air, sat with blankets and chairs on the observatory's great lawn. "It's really a celestial festival out here," John Peter, 39, told the Los Angeles Times as he set up his camera. Lying on a slope north of downtown near the Hollywood sign, the place offers clear views of the sky. Observatory officials alerted the crowd when the eclipse began and spontaneous applause erupted whenthe celestial ended. A total lunar eclipse occurs when the moon goes through the long shadow cast by the Earth and is blocked from the sunlight that brightens it.
