Comet ISON, SOHO clip

Videonummer 11936587

Comet ISON. Solar and Heliospheric Observatory (SOHO) footage of Comet ISON (moving object, white) passing close to the Sun in November 2013. The time and date are shown at lower left, as well as the name of the instrument used: LASCO (Large Angle and Spectrometric Coronagraph). C3 refers to the white-light coronagraph (blue), imaging from 3.7 to 32 solar radii. Discovered in 2012 using the International Scientific Optical Network (ISON), it was predicted that comet ISON would be one of the brightest comets in history as it passed Earth in 2013. However, most of comet ISON disintegrated as it approached its perihelion (the point at which it passes closest to the Sun) on 28 November 2013. It is thought that this is because it was not large enough to withstand its trajectory around the Sun. The second half of the clip shows a close-up of the perihelion passage. The SOHO footage also shows the solar atmosphere (the corona, white). This footage is combined in a composite with a central image of the Sun (yellow) from the Solar Dynamics Observatory (SDO).
