While observers in North America will enjoy views of a\u00a0total solar eclipse later today<\/a>\u00a0as the Moon slips between Earth and the Sun, it\u2019s business as usual for our Proba-2 and SOHO satellites.<\/span><\/p>\n

Proba-2<\/a>\u00a0is expected to capture a series of partial eclipses, while SOHO will provide context images of the Sun and its extended atmosphere, or corona. The corona can only be seen from Earth with the naked eye during an eclipse when the Moon blocks out the bright light from the Sun, but SOHO can observe it all the time using special filters and \u2018occulting masks\u2019.<\/span><\/p>\n

An example can be seen here, which is a composite of two SOHO images and a Proba-2 image taken earlier this morning, and composed using\u00a0JHelioviewer<\/a>. The central image shows an extreme-ultraviolet image of the solar disc taken by Proba-2 at 05:39 GMT, while the corona and extended atmospheric features are seen by SOHO in the red image from 2\u20136 solar radii, and beyond in blue (SOHO can see up to about 32 solar radii) at 00:48 and 00:54 GMT, respectively. The black circular region corresponds to an occulting mask to cut out direct sunlight that would otherwise obscure the details close to the Sun \u2013 similar to the effect of the Moon in a total solar eclipse.<\/span><\/p>\n

Near-realtime images of the Sun from SOHO are always available\u00a0here<\/a>, and in the days leading up to today\u2019s total eclipse\u00a0these frequent images<\/a>\u00a0give scientists an idea of how the corona will look during their observations. This enables them to plan specific observations of any special regions of interest, and in the context of the state of the Sun\u2019s activity.<\/span><\/p>\n

A team of dedicated\u00a0astronomers from ESA<\/a>\u00a0will be studying the eclipse from the path of totality in the USA, hoping for clear skies to capture this celestial spectacular.<\/span><\/p>\n

In addition, astronauts aboard the International Space Station, including ESA\u2019s Paolo Nespoli, should also be able to see\u00a0some aspects of the eclipse,<\/a>\u00a0such as a partial eclipse and the shadow of the Moon on the surface of our planet.<\/span><\/p>\n

Remember: never look directly at the Sun, even when partially eclipsed, without proper eye protection such as special solar eclipse glasses, or you risk permanent eye damage.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
