Question: What regime followed the rule of the man who was guillotined in the French Revolution over the country that approved the name of the planet featuring the Small Dark Spot?

<P0-S0> 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). <P0-S1> much more convincing is giovanni cassini's description of a "permanent spot" the following year. <P0-S2> 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. <SEP> <P1-S0> The National Convention had convicted the king (17 January 1792) in a near - unanimous vote (while no one voted`` not guilty'', several deputies abstained) and condemned him to death by a simple majority. <P1-S1> The execution of Louis XVI, by means of the guillotine, a major event of the French Revolution, took place on 21 January 1793 at the Place de la Révolution (``Revolution Square '', formerly Place Louis XV, and renamed Place de la Concorde in 1795) in Paris. <SEP> <P2-S0> the scooter is another storm, a white cloud group farther south than the great dark spot. <P2-S1> 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). <P2-S2> the small dark spot is a southern cyclonic storm, the second-most-intense storm observed during the 1989 encounter. <P2-S3> 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. <SEP> <P3-S0> 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. <P3-S1> 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. <P3-S2> French almanacs quickly reintroduced the name Herschel for Uranus, after that planet's discoverer Sir William Herschel, and Leverrier for the new planet. <P3-S3> This suggestion met with stiff resistance outside France. <SEP> <P4-S0> It was the second most intense storm on the planet in 1989, when "Voyager 2" flew by the planet. <P4-S1> When the Hubble Space Telescope observed Neptune in 1994, the storm had disappeared. <P4-S2> The Small Dark Spot, sometimes also called Dark Spot 2 or The Wizard's Eye, was a southern cyclonic storm on the planet Neptune. <SEP> <P5-S0> Charles-Henri Sanson, full title "Chevalier Charles-Henri Sanson de Longval" (15 February 1739 – 4 July 1806), was the royal executioner of France during the reign of King Louis XVI, and High Executioner of the First French Republic. <P5-S1> He administered capital punishment in the city of Paris for over forty years, and by his own hand executed nearly 3,000 people, including the King himself.
