The Chinese Zijin Mountain Observatory sent an expedition to Lintao to observe this eclipse. The expedition team traveled 3200 kilometres and 43 days to reach the observation point. Over the expedition, they often found themselves in the shadow of…
The renowned Russian chemist Dmitri Mendeleev ascended in a hot balloon in a field near Klin to observe this eclipse. Despite that Mendeleev had never manoeuvred an air ballon before, the rainy weather forced him to fly alone. The balloon eventually…
The Royal Astronomical Society intended to organise and two eclipse expeditions, spread across from French Guyana to the then Portuguese colony of Angola on this date to observe changes in the solar corona. However, Brown organised a third unofficial…
Maria Mitchell, professor at Vassar College, along with five of her students observed the total solar eclipse from Denver, Colorado. Her expedition promoted the discussion of women's involvement and science and the political issues surrounding this.
A Concord 001 with seven observers in followed the path of totality across North Africa during the total solar eclipse. They achieved 74 minutes of totality. The jet flew at a speed of Mach 2.05 at an altitude of between 16,200 and 17,700 metres.…
With Siam surrounded by British territories in the West and French territories in the East, King Rama IV strategically invited Sir Harry Ord, a British military diplomat to his expedition in Siam and also independently granted a French expedition…
French astrophysicist Jules Janssen used spectroscopy to analyse the light spectra data from the solar prominences during totality. He observed the expected Fraunhofer lines due to presence of hydrogen and sodium in the Sun. However, he also noticed…
Coronium, a predicted chemical element, was detected during the total solar eclipse of 7 August, 1869, when astronomers Charles Augustus Young and William Harkness independently observed a green emission line in the coronal spectrum during the…
After almost 27 years after it was first detected in the chromosphere during the total solar eclipse of 18 August 1868 in India, Sir William Ramsay, a Scottish chemist, isolated the element whilst treating a sample of the mineral cleveite.
British astronomer and chemist Warren de la Rue designed the first photoheliograph - an instrument that consisted of features from a telescope and camera. He then transported this along with a mobile photo studio and dark room from Plymouth to…
Julius Berkowski, a renowned photographer, is credited for capturing the first successful photographic image of the solar corona (with the correct exposure) during this solar eclipse using a technique called "the daguerreotype process". He was…
An expedition from the Greenwich Observatory and a joint Dutch-German expedition traveled to Christmas island to make observations of the total solar eclipse in May 1922. Both teams sought confirmatory evidence for Albert Einstein's Theory of General…
The Sydney Observatory sent a team to Goondiwindi, in Queensland, east Australia, in an expedition organised and financed by Sir Wilfrid Russell Grimwade.

The Observatory in Adelaide, South Australia sent a party to the Cordillo Downs, to make observations at the total solar eclipse in Australia in 1922. Transporting their supplies and equipment took over a month to do due to its extremely remote…
The Lick Observatory of California, Perth Observatory, University of Toronto and Kodiakanal Solar Observatory all sent expeditions to remote Wallal after the Commonwealth Government offered to provide transport to and from the location. The local…
An expedition organised by the Carnegie Institution of Washington also sent an expedition to Cape Palmas, Liberia, with the primary goal to investigate the magnetic effects of the Sun. They found that the eclipse had a clear influence on Earth’s…
The Principe party of the expedition organised by the Joint Permanent Eclipse Committee in England to measure the deflection of stellar rays by the Sun's gravitational field. Whilst misfortune negatively affected their observations, this expedition…
Observers from the Greenwich Observatory in England, the Bureau des Longitudes in France and Brazilian National Observatory congregated at a site in Pasa Quatro to independently make observations at the total solar eclipse in 1912. Although on the…
Separate expeditions from the Argentine National Observatory and the National Astronomical Observatory in Chile sent separate expeditions to Cristina to make observations at the total solar eclipse of 10 October, 1912. Their agendas for the eclipse…
The Argentine National Observatory sent an expedition in their second attempt to measure the deflection of stellar rays by the Sun. They were meant to be joined by a expedition from the Berlin Observatory led by Freundlich, however due to the…
An expedition team sent by the Joint Permanent Eclipse Committee traveled to the Russian Empire, but their agenda for the eclipse was clouded out. They were also forced to leave their equipment in the Empire due to the start of the First World War,…
A team from the Lick Observatory in California, alongside their original plan for the eclipse, were prepared to perform the experiment to measure the deflection of stellar rays in order to verify Einstein's theories on the deflection of light. Due to…
The Joint Permanent Eclipse Committee in England sent two parties across the world to measure the deflection of stellar rays by the Sun's gravitational field. Their expeditions are perhaps the most famous eclipse expeditions of all time and their…
After the Jesuit Fathers of the efforts by the Joint Permanent Eclipse Committee to send an expedition party to Minsk were refused entry into the Russian Empire, the expedition was divided into two and an expedition party instead went north to Sweden…
