Российские ученые будут наблюдать в воскресенье полное солнечное затмение на острове Пасхи в Тихом океане. Экспедиция организована Институтом солнечно-земной физики Сибирского отделения РАН и астрономической обсерватории Иркутского государственного университета с участием Российского географического общества при поддержке Российского фонда фундаментальных исследований.
Как сообщил в штабе экспедиции, в текущем году в зону полного солнечного затмения с максимальной продолжительностью 5 минут 20 секунд и шириной полосы более 200 километров попадает южная часть Тихого океана - острова Кука, атоллы Французской Полинезии, остров Пасхи, юг Чили и Аргентины. "Остров Пасхи выбран потому, что здесь Солнце в момент затмения будет высоко над горизонтом, и это позволит получить качественные снимки солнечной короны", - отметили в штабе.
По словам научного руководителя экспедиции Сергея Язева, нынешние наблюдения проводятся на ранней стадии развития цикла солнечной активности сразу после окончания аномально затянувшегося периода пониженной активности. В частности, ученых интересуют спектральные измерения: так называемый спектр вспышки и спектр солнечной короны, что даст возможность продолжить исследования зависимости формы короны от фазы цикла активности земного светила.
Если повезет с погодой, считают сибирские астрофизики, то результаты экспедиции пополнят имеющуюся у них базу данных по ряду предыдущих затмений. В 2006 году они наблюдали полный заход Солнца за Луну на пике Терскол в Приэльбрусье, 2008 редкое зрелище предстало перед ними на юго-западе Монголии - по соседству с пустыней Гоби, а год назад - на островах архипелага Кирибати на том же Тихом океане, сообщает ИТАР-ТАСС.

Summary: On July 11, 2010, the new Moon passed directlly in front of the sun, producing a solar eclipse of rare beauty across the South Pacific. The path of totality crossed the Cook islands, Easter island, the waters off Tahiti, and southern parts of Argentina and Chile. [full story] [animated eclipse maps]
Fantastic moment on the feet of the Ahu NauNau Moais. Weather got clear the same morning of the clipse, fantastic and unreal !

Taken from the South of Anaa Atoll on the Astro Expeditions tour. A small section from the main group set off on a pre-dawn convoy of 3 small but very powerful speedboats for a bone jarring 20 miles trip to the South of the remote Atoll where we enjoyed an extra 30 seconds of totality in stunning surroundings. Canon 40D, 24mm lens, 1/15th Sec.
Eclipse 2010 Composite A solar eclipse photo (gray and white) from the Williams College Expedition to Easter Island in the South Pacific (July 11, 2010) was embedded into an image of the Sun's outer corona taken by the Large Angle Spectrometric Coronagraph (LASCO) and shown in red false color. LASCO uses a disk to blot out the bright sun and the inner corona so that the faint outer corona can be monitored and studied. Further, the dark silhouette of the moon was covered with an image of the Sun taken in extreme ultraviolet light at about the same time by NASA's Solar Dynamics Observatory (SDO). The composite brings out the correlation of structures in the inner and outer corona. Credits: Williams College Eclipse Expedition -- Jay M.

Janne Pyykkö, El Calafate, Patagonia, Argentina Jul. 11, 2010#1
The total solar eclipse 11-July-2010 in Argentina was not easy-to-catch, because the total phase appeared only 1 degree above the horizon and above the usually-cloudy Andes. To increase my possibilities, I hiked to a hill 400 meters above the lake Lago Argentino. With luck in weather I catched the phenomenon just over the mountains. I put myself into the photo to get a human touch. There was quite a strong wind during the eclipse which made me wish I had a better tripod.
Physics professor Patricia Reiff of Rice University witnessed the eclipse from the deck of the Aranui 3 cruise ship just off the coast of Tahiti. She sent these pictures directly from the ship using her iPhone.
The shadow of the Moon sweeping over Patagonia in southern Argentina plunges the steppe east of El Calafate into darkness just before sunset on 11 July 2010. The sharp delineation of the Moon's umbra in the sky stunned everyone. Pictures taken with compact camera at various zoom settings.

Our group flew to this remote atoll (consisting of a coral reef surrounding a lagoon) about 550 miles east of Tahiti. The weather was perfect and the seeing was superb. The local people gave us a warm welcome with Polynesian dances. Photo details: Canon 7D with Takahashi FSQ-106ED, 400 ISO.

11th July was my birthday and this was the second (and last) eclipse on my birthday in my lifetime. These images were taken from Hao Atoll,French Polynesia. I used my trusty vintage 1975 400mm telephoto with a Canon 300D. Images of the chromosphere just after 2nd contact, inner corona and prominences mid eclipse and the 3rd contact diamond ring. We had very thin cloud and a pesky thicker patch just at the end. Shadow bands were visible on the sand just after 3rd contact.

A group of about 40 international travellers, including 14 Canadians, were at the airport on Hikueru atoll in the Tuamotu chain of atolls in French Polynesia. Unfortunately, cloud moved in at the wrong time (just at second contact) and obscured the Sun through totality. Had the eclipse occurred 5 minutes earlier we would have seen it. People further down the island in the village did see the eclipsed Sun in the clear -- the cloud was that low and local. The fish-eye shot shows the entire sky (most of it clear and with stars showing) at the moment of second contact diamond ring.
Six separate exposures from 1/500 to 1/15 second were digitally combined to create the image of the corona. I used a Nikkor 300 mm f/4 lens with a Nikon D300 at ISO 200. The third contaact and Baily's Bead images were 1/8000 second exposures. The diamond ring exposure was 1/500 second. For the wide angle image I used a Nikon D70 with a 18-200 mm f/3.5-5.6 lens working at 18 mm and f/3.5, with a 1/4 second exposure at ISO 400.
