These rare events have been historically important for astronomers in trying to determine the distance of the Sun from the Earth. In theory, this distance can be calculated by observing a transit from different locations. This method was first suggested in 1677 by United Kingdom&rsquo;s Astronomer Royal, Edmond Halley. For the coming opportunities of observing a transit of Venus (in 1761 and 1769), challenging and sometimes tragic overseas expeditions were organised.&nbsp;In 1761, a thin arc of light \u2013 encircling the planet at the beginning and end of the transit, on the portion projected outside the Solar limb \u2013 was detected for the first time, and <a href=\"https:\/\/sites.lesia.obspm.fr\/thomas-widemann\/files\/2019\/11\/chappe.pdf\">further described<\/a> in 1769 as caused by an atmosphere around Venus.<\/p>\n\n\n\n<p>In 2004, the first transit since 1882, this <em>aureole<\/em> created by the halo of atmosphere around Venus immediately before and immediately after the transit was <a href=\"https:\/\/sites.lesia.obspm.fr\/thomas-widemann\/files\/2019\/11\/Pasachoff_etal2011.pdf\">rediscovered<\/a>. The brightness of the aureole, and its evolution over time outside of the solar disk could be reproduced by modeling the refraction (bending) of light in the planet\u2019s atmosphere. On June 5-6, 2012, Paolo Tanga (Observatoire de la c\u00f4te d&rsquo;Azur, Nice) and myself used a variety of acquisition systems to record the aureole photometry \u2013 ranging from amateur-sized to telescopes and cameras to NASA and JAXA Earth-orbiting solar telescopes \u2013 thus collecting for the first time a large amount of quantitative information on this atmospheric phenomenon. In <a href=\"https:\/\/sites.lesia.obspm.fr\/thomas-widemann\/files\/2019\/11\/Tanga_etal2012.pdf\">Tanga et al. (2012)<\/a> we have shown that the aureole photometry reflects the local density scale height and the altitude of the refracting layer.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter is-resized\"><a href=\"https:\/\/sites.lesia.obspm.fr\/thomas-widemann\/files\/2019\/11\/Transit_line-e1459836472406.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/sites.lesia.obspm.fr\/thomas-widemann\/files\/2019\/11\/Transit_line-e1459836472406.jpg\" alt=\"\" class=\"wp-image-856\" width=\"631\" height=\"203\" srcset=\"https:\/\/sites.lesia.obspm.fr\/thomas-widemann\/files\/2019\/11\/Transit_line-e1459836472406.jpg 810w, https:\/\/sites.lesia.obspm.fr\/thomas-widemann\/files\/2019\/11\/Transit_line-e1459836472406-300x97.jpg 300w, https:\/\/sites.lesia.obspm.fr\/thomas-widemann\/files\/2019\/11\/Transit_line-e1459836472406-768x247.jpg 768w, https:\/\/sites.lesia.obspm.fr\/thomas-widemann\/files\/2019\/11\/Transit_line-e1459836472406-150x48.jpg 150w, https:\/\/sites.lesia.obspm.fr\/thomas-widemann\/files\/2019\/11\/Transit_line-e1459836472406-250x81.jpg 250w\" sizes=\"auto, (max-width: 631px) 100vw, 631px\" \/><\/a><figcaption>Aureole at ingress observed with the Cytherograph in Lowell Observatory,  AZ during the transit of Venus on 5 June 2012.

The positions of the contacts (I to IV) are indicated, as well as the orbit of European Space Agency\u2019s Venus Express orbiter around the planet, projected to scale. Venus is shown at its location during orbit 2238 when SOIR data were collected at the time of apparent solar ingress at 49.33N on evening terminator at 6.075PM Local Solar Time (LST). At the scale used in Fig. 1, the parallax effect from a site on the Earth surface, or from the position of SDO, is negligible. For data reduction, accurate positions of Venus relative to the Solar limb are derived directly from HDO\/HMI images.<\/p>\n\n\n\n<p>The instruments used for the 2012 campaign were specifically adapted portable telescopes equipped with a Lyot coronograph, a device that hides the solar disk to enhance the contrast of the faint aureole, and using different filters to studying the Venus transit at several different wavelengths. By deploying this unique instrument, we were proud to honor a three-century long tradition at Paris Observatory with Joseph-Nicolas Delisle (1688-1768) for the transits of 1761 and 1769, and Jules Janssen (1824-1907) for the transits of 1874 and 1882.
