| 释义 |
A annular solar eclipse occurred on January 11, 1842 during summer. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. It was the first of three solar eclipses that took place that year, the next was a total eclipse on July 8, 1842 and covered almost all of the Northern Hemisphere.[1] It was the solar saros 119 cycle of eclipses[2] DescriptionThe eclipse was visible in much of the three southern oceans including the southeast part of the Pacific, most of the South Atlantic Ocean and its islands and small parts of the Indian Ocean surrounding Antarctica with a tiny bit probably excluded. It also included the southern tip of South America which included Patagonia and the Falkland Islands and the Cape Colony (now Southern and Northern Cape which are part of South Africa). It showed 30% obscuration at Ushuaia and the Falklands (or Malvinas), 50% around the South Georgia, South Orkney and Livingston Islands, 60% at the north of the Antarctic Peninsula and 80% in the middle part. The rim of the eclipse included southeast of Tuamotu Islands, Puerto Montt and areas south of Buenos Aires. The eclipse started at sunrise offshore from New Zealand and ended at sunset in a smaller part of southern Africa. The greatest eclipse was in midcentral Antarctica at 75.8 S and 1.4 E some kilometers from the Prime Meridian at 16:25 UTC[1] The duration was 6 min 15 seconds and showed 91.5% obscuration of the sun.
