Question: When did the country that approved the first name of the planet with the Small Dark Spot sign an armistice with Germany?

full_context: Document 1: Voyager 2: While in the neighborhood of Neptune, Voyager 2 discovered the ``Great Dark Spot '', which has since disappeared, according to observations by the Hubble Space Telescope. Originally thought to be a large cloud itself, the`` Great Dark Spot'' was later hypothesized to be a hole in the visible cloud deck of Neptune.
Document 2: Neptune: The Scooter is another storm, a white cloud group farther south than the Great Dark Spot. This nickname first arose during the months leading up to the Voyager 2 encounter in 1989, when they were observed moving at speeds faster than the Great Dark Spot (and images acquired later would subsequently reveal the presence of clouds moving even faster than those that had initially been detected by Voyager 2). The Small Dark Spot is a southern cyclonic storm, the second-most-intense storm observed during the 1989 encounter. It was initially completely dark, but as Voyager 2 approached the planet, a bright core developed and can be seen in most of the highest-resolution images.
Document 3: Discovery of Neptune: The planet Neptune was mathematically predicted before it was directly observed. With a prediction by Urbain Le Verrier, telescopic observations confirming the existence of a major planet were made on the night of September 23 -- 24, 1846, at the Berlin Observatory, by astronomer Johann Gottfried Galle (assisted by Heinrich Louis d'Arrest), working from Le Verrier's calculations. It was a sensational moment of 19th century science and dramatic confirmation of Newtonian gravitational theory. In François Arago's apt phrase, Le Verrier had discovered a planet ``with the point of his pen ''.
Document 4: Neptune: Neptune is not visible to the unaided eye and is the only planet in the Solar System found by mathematical prediction rather than by empirical observation. Unexpected changes in the orbit of Uranus led Alexis Bouvard to deduce that its orbit was subject to gravitational perturbation by an unknown planet. Neptune was subsequently observed with a telescope on 23 September 1846 by Johann Galle within a degree of the position predicted by Urbain Le Verrier. Its largest moon, Triton, was discovered shortly thereafter, though none of the planet's remaining known 14 moons were located telescopically until the 20th century. The planet's distance from Earth gives it a very small apparent size, making it challenging to study with Earth-based telescopes. Neptune was visited by Voyager 2, when it flew by the planet on 25 August 1989. The advent of Hubble Space Telescope and large ground-based telescopes with adaptive optics has recently allowed for additional detailed observations from afar.
Document 5: Neptune: In contrast to the hazy, relatively featureless atmosphere of Uranus, Neptune's atmosphere has active and visible weather patterns. For example, at the time of the Voyager 2 flyby in 1989, the planet's southern hemisphere had a Great Dark Spot comparable to the Great Red Spot on Jupiter. These weather patterns are driven by the strongest sustained winds of any planet in the Solar System, with recorded wind speeds as high as 2,100 kilometres per hour (580 m/s; 1,300 mph). Because of its great distance from the Sun, Neptune's outer atmosphere is one of the coldest places in the Solar System, with temperatures at its cloud tops approaching 55 K (−218 °C). Temperatures at the planet's centre are approximately 5,400 K (5,100 °C). Neptune has a faint and fragmented ring system (labelled "arcs"), which was first detected during the 1960s and confirmed by Voyager 2.
Document 6: Small Dark Spot: The Small Dark Spot, sometimes also called Dark Spot 2 or The Wizard's Eye, was a southern cyclonic storm on the planet Neptune. It was the second most intense storm on the planet in 1989, when "Voyager 2" flew by the planet. When the Hubble Space Telescope observed Neptune in 1994, the storm had disappeared.
Document 7: Armistice of 22 June 1940: The Armistice of 22 June 1940 was signed at 18: 36 near Compiègne, France, by officials of Nazi Germany and the French Third Republic. It did not come into effect until after midnight on 25 June.
Document 8: Armistice of Cassibile: The Armistice of Cassibile was an armistice signed on 3 September 1943 by Walter Bedell Smith and Giuseppe Castellano, and made public on 8 September, between the Kingdom of Italy and the Allies of World War II. It was signed at a conference of generals from both sides in an Allied military camp at Cassibile in Sicily, which had recently been occupied by the Allies. The armistice was approved by both King Victor Emmanuel III and Italian Prime Minister Pietro Badoglio. The armistice stipulated the surrender of Italy to the Allies.
Document 9: Neptune: Meanwhile, Le Verrier by letter urged Berlin Observatory astronomer Johann Gottfried Galle to search with the observatory's refractor. Heinrich d'Arrest, a student at the observatory, suggested to Galle that they could compare a recently drawn chart of the sky in the region of Le Verrier's predicted location with the current sky to seek the displacement characteristic of a planet, as opposed to a fixed star. On the evening of 23 September 1846, the day Galle received the letter, he discovered Neptune within 1° of where Le Verrier had predicted it to be, about 12° from Adams' prediction. Challis later realised that he had observed the planet twice, on 4 and 12 August, but did not recognise it as a planet because he lacked an up-to-date star map and was distracted by his concurrent work on comet observations.
Document 10: Great Red Spot: For example, its first sighting is often credited to Robert Hooke, who described a spot on the planet in May 1664; however, it is likely that Hooke's spot was in another belt altogether (the North Equatorial Belt, versus the current Great Red Spot's location in the South Equatorial Belt). Much more convincing is Giovanni Cassini's description of a "permanent spot" the following year. With fluctuations in visibility, Cassini's spot was observed from 1665 to 1713; however, the 118-year observational gap makes the identity of the two spots inconclusive, and the older spot's shorter observational history and slower motion than the modern spot make their identity unlikely.
Document 11: Neptune: Most languages today, even in countries that have no direct link to Greco-Roman culture, use some variant of the name "Neptune" for the planet. However, in Chinese, Japanese, and Korean, the planet's name was translated as "sea king star" (海王星), because Neptune was the god of the sea. In Mongolian, Neptune is called Dalain Van (Далайн ван), reflecting its namesake god's role as the ruler of the sea. In modern Greek the planet is called Poseidon (Ποσειδώνας, Poseidonas), the Greek counterpart of Neptune. In Hebrew, "Rahab" (רהב), from a Biblical sea monster mentioned in the Book of Psalms, was selected in a vote managed by the Academy of the Hebrew Language in 2009 as the official name for the planet, even though the existing Latin term "Neptun" (נפטון) is commonly used. In Māori, the planet is called Tangaroa, named after the Māori god of the sea. In Nahuatl, the planet is called Tlāloccītlalli, named after the rain god Tlāloc.
Document 12: Neptune: Claiming the right to name his discovery, Le Verrier quickly proposed the name Neptune for this new planet, though falsely stating that this had been officially approved by the French Bureau des Longitudes. In October, he sought to name the planet Le Verrier, after himself, and he had loyal support in this from the observatory director, François Arago. This suggestion met with stiff resistance outside France. French almanacs quickly reintroduced the name Herschel for Uranus, after that planet's discoverer Sir William Herschel, and Leverrier for the new planet.
Document 13: Philippe Pétain: With the imminent Fall of France in June 1940 in World War II, Pétain was appointed President of the Ministerial Council by President Lebrun at Bordeaux, and the Cabinet resolved to sign an armistice agreement with Germany. The entire government subsequently moved briefly to Clermont-Ferrand, then to the spa town of Vichy in central France. His government voted to transform the discredited French Third Republic into the French State, an authoritarian regime that collaborated with the Axis, although it refused to declare war on the UK after the attack on Mers-el-Kebir and even remained formally at war with Germany. After Germany and Italy occupied and disarmed France in November 1942, Pétain became a mere puppet of the German military administration.
Document 14: Armistice of 11 November 1918: The Armistice of 11 November 1918 was the armistice that ended fighting on land, sea and air in World War I between the Allies and their last opponent, Germany. Previous armistices had eliminated Bulgaria, the Ottoman Empire and the Austro - Hungarian Empire. Also known as the Armistice of Compiègne from the place where it was signed, it came into force at 11 a.m. Paris time on 11 November 1918 (``the eleventh hour of the eleventh day of the eleventh month '') and marked a victory for the Allies and a complete defeat for Germany, although not formally a surrender.
Document 15: Franco-Prussian War: Although public opinion in Paris was strongly against any form of surrender or concession to the Prussians, the Government realised that it could not hold the city for much longer, and that Gambetta's provincial armies would probably never break through to relieve Paris. President Trochu resigned on 25 January and was replaced by Favre, who signed the surrender two days later at Versailles, with the armistice coming into effect at midnight. Several sources claim that in his carriage on the way back to Paris, Favre broke into tears, and collapsed into his daughter's arms as the guns around Paris fell silent at midnight. At Tours, Gambetta received word from Paris on 30 January that the Government had surrendered. Furious, he refused to surrender and launched an immediate attack on German forces at Orleans which, predictably, failed. A delegation of Parisian diplomats arrived in Tours by train on 5 February to negotiate with Gambetta, and the following day Gambetta stepped down and surrendered control of the provincial armies to the Government of National Defence, which promptly ordered a cease-fire across France.
