This is the Total Solar Eclipse 2019 results webpage, from the CESAR expedition to La SIlla Observatory, ESO, Chile, on 02-Jul-2019. CESAR organized a SPECIAL EVENT on the 02 July, 2019. A CESAR Expedition travelled to Chile to cover the event. It was broadcast LIVE from ESAC (European Space Agency Center) with live conections to Chile, experts talks and briefings, and Q&A. Totality happened at 22:42 local time in La SIlla, Chile, 20:42 in local time Europe CEST. More details on the preparations, location and equipment used in the expedition can be found here. Questions and answers for eclipses here. NOTE Images can be used under the terms and conditions of the CC BY-SA 3.0 IGO licence. Click on images for high-res versions. |

A composite of space- and ground-based observations gathered at the time of the solar eclipse on 2 July 2019, combining imagery from the ESA/NASA SOHO and ESA's Proba-2 satellites with observations performed by the ESA-CESAR team in Chile.
At the centre, an extreme-ultraviolet image of the solar disc taken by the Royal Observatory of Belgium’s SWAP instrument aboard ESA’s Proba-2 mission shows the surface of the Sun (depicted in grey scale). The surrounding inner corona (also shown in grey scale) is revealed through ground-based observations obtained during the totality phase of the eclipse with a 10-cm refractor telescope (600mm focal lenght) at ESO’s La Silla Observatory in Chile. The outer corona is depicted through the white-light LASCO-C2 (shown in red) and C3 (shown in blue) coronagraph instruments aboard the ESA/NASA SOHO satellite. The composite image provides an overall view of the Sun and its surrounding corona, with several streamers – elongated structures that extend from the solar surface far out into space. It shows the power of combining ground-based observations of the corona, which provide fine details of the inner corona and can only be obtained during a total eclipse, with the broader context yielded by coronographs like those on SOHO, which can observe the wider corona. |

| The eclipse in 3D. The total solar eclipse of 2 July 2019, composed for viewing with red-green/blue '3D' anaglyph glasses. The image combines the first and last image during totality and has a subtle 3D effect. The right image is an animated GIF to show the actual images of the anaglyph and how much the moon moves |

UV response |

| The blocking in UV. The plot shows a near-UV sensor and a solar cell (which responds to visible, near-IR light). The minor difference between them is due to the different opacity of the atmosphere vs elevation. Credit: Ralph Lorenz. |

| The blocking Moon. The full disk of the Moon is lit by Earth's reflected light from the Sun. Moon's visible face is clearly distinguished, despite the ultra faint shine, using a processed over-exposed image, telescope ~1000mm, 2sec, ISO 1800. Canon 550D |

Stars identified in the corona region |
 Stars during totality. Several stars are identified within the extended corona, at distances less than 3 Sun's diameters |
