Designated Uranus XVI it was named after the monster fictional character in William Shakespeare's play "The Tempest".
The orbital parameters suggest that it may belong, together with Stephano to the same dynamic cluster, suggesting common origin.
The diameter is estimated at 72 km (assuming albedo of 0.04), making it the second biggest non-spherical moon of Uranus, half the size of Sycorax, the biggest non-spherical moon of Uranus.
The light curve suggests Caliban's rotation period is 2.7 hours.
Tropical cyclone forecast model
A tropical cyclone forecast model is a computer program that uses meteorological data to forecast where tropical cyclones will go and how strong they will be. Models use powerful supercomputers and mathematical modeling software. There are two general types: statistical and dynamic. There are two main types of forecasts: track and intensity.
Villalba, Puerto Rico
Villalba (vee-YAHL-bah) is a municipality of Puerto Rico. It is in the central region, northeast of Juana Díaz; south of Orocovis; and west of Coamo. Villalba is spread over 6 wards and Villalba Pueblo (the downtown area and the administrative center of the city).
Stephano (moon)
Stephano is a retrograde non-spherical moon of Uranus. It was found by Brett J. Gladman, "et al." in 1999, and given the designation S/1999 U 2.
Confirmed as Uranus XX, it is named after the drunken butler in William Shakespeare's play "The Tempest".
Trinculo (moon)
Trinculo is a retrograde non-spherical moon of Uranus. It was found by Holman, "et al." on 2001-08-13, and given the designation S/2001 U 1.
Confirmed as Uranus XXI, it was named after the drunken jester Trinculo in William Shakespeare's play "The Tempest".
Cabo Engaño
Cabo Engaño is a cape near Punta de Agua, the easternmost point of the island of Hispaniola, in the Dominican Republic. The region around the cape is very dry where cacti grow.
Christopher Columbus saw the cape for the first time on 16 January 1493 and named it as Cape Sant Theramo (or Cape San Telmo).
Punta Cana International Airport, one of the busiest airport of the country, is to the south of the cape.
Sycorax (moon)
Sycorax is one of Uranus' moons. It is the biggest retrograde non-spherical one of its moons.
Sycorax was found on September 6, 1997 by Brett J. Gladman, Philip D. Nicholson, Joseph A. Burns, and John J. Kavelaars. They found it using the 200-inch Hale telescope. They also found Caliban. Sycorax was given the designation S/1997 U 2.
Sycorax was confirmed as Uranus XVII. It was named after Sycorax, Caliban's mother in William Shakespeare's play "The Tempest".
Sycorax follows a far orbit, more than 20 times farther from Uranus than the farthest regular moon Oberon. Its orbit is retrograde, moderately inclined and eccentric.
The orbital parameters suggest that it may belong, together with Setebos and Prospero, to the same dynamic cluster, suggesting common origin.
The diagram illustrates the orbital parameters of the retrograde non-spherical moons of Uranus (in polar co-ordinates) with the eccentricity of the orbits represented by the segments extending from the pericentre to the apocentre.
The diameter of Sycorax is estimated at 150 km (assuming albedo of 0.04) making it the biggest non-spherical moon of Uranus, comparable in size with Himalia, the biggest non-spherical moon of Jupiter.
The rotation period could not be estimated well (best fit ~4 h).
Wozzeck
Wozzeck is an opera by the Austrian composer Alban Berg (1885-1935). It was composed between 1914 and 1922 and first performed in 1925.
Berg wrote this opera before the period when he used serialism in his works. His teacher Schoenberg had not yet developed the twelve tone system. The music of "Wozzeck" has tonal music in the tradition of Mahler, but also some atonal music (music which is not based on any key) as well as melodies which are based on the whole tone scale. The music sounded very modern at the time it was written. Berg also writes for the voices in unusual ways: sometimes they have to half-speak, half-sing (this is called Sprechgesang).
The opera is based on a play called "Woyzeck" by the German playwright Georg Büchner. "Woyzeck" was an unusual drama because, instead of being a story about someone important such as a king or a god, it was about a poor man who is not very smart and is bullied and misused by other people. When Berg wrote the opera nearly a century later, it was still an unusual story for an opera. The heroes in operas were usually important people, while working people often had comic parts: they were often servants. But Wozzeck is a simple man who cannot help what is happening to him. In drama this is sometimes called an "anti-hero".
Scene 1 (Suite): Wozzeck is working as a barber. While he is shaving the Captain, the Captain tells Wozzeck that he thinks Wozzeck leads a bad life because he has had a child with a woman (Marie) without being married to her. Wozzeck says that it is hard for him to be good because he is poor. He reminds the Captain that Jesus said "Let the little children come to me," (Mark 10:14). The Captain is confused by this remark.
Scene 2 (Rhapsody and Hunting Song): Wozzeck and his friend Andres are cutting sticks as the sun is setting. Wozzeck has scary visions: he sees the sinking sun covering the world in flames.
Scene 3 (March and Lullaby): Soldiers march by outside Marie's room. Her neighbour, Margret, tells Marie she is bad because she is with the soldiers. Then Wozzeck comes and tells Marie of the terrible visions he has had.
Scene 4 (Passacaglia): The Doctor tells Wozzeck that he should not cough in the street (Büchner wrote: “piss in the street”). He says he is doing a medical experiment. Wozzeck is so simple that he believes him. The doctor is glad to hear about Wozzeck’s terrible visions.
Scene 5 (Rondo): Marie admires the Drum-major outside her room. He wants to love her. At first she turns away from him, but then she gives in and they rush out together.
Scene 1 (Sonata-Allegro): Marie is telling her child to go to sleep while admiring earrings which the Drum-major gave her. Wozzeck arrives. He asks her where she got the earrings. She says she found them. Wozzeck does not know whether to believe her, but gives her some money and leaves. Marie knows her behaviour is wrong.
Scene 2 (Fantasia and Fugue on 3 Themes): The Doctor rushes by the Captain in the street, who tells him to slow down. The Doctor makes the Captain frightened by thinking of nasty illnesses that he might get. When Wozzeck comes, they tease him by saying that Marie loves someone else.
Scene 3 (Largo): Wozzeck talks about it to Marie. She admits that she has a boyfriend. Wozzeck is furious. He is about to hit her when she stops him, saying even her father never dared to hit her. She says: "better a knife in my belly than your hands on me". This gives Wozzeck an idea for revenge.
Scene 4 (Scherzo): Wozzeck sees Marie dancing with the Drum-major in a crowd. Andres asks Wozzeck why he is sitting by himself. A drunkard gives a sermon, then an idiot goes up to Wozzeck and says he can smell blood.
Scene 5 (Rondo): In the barracks at night, Wozzeck cannot sleep. He is keeping Andres awake. The Drum-major comes in. He is drunk. He gets Wozzeck out of bed to fight with him.
Scene 1 (Invention on a Theme): In her room at night, Marie reads to herself from the Bible. She wants to be forgiven.
Scene 2 (Invention on a Single Note (B)): Wozzeck and Marie are walking in the woods by a pond. Marie wants to leave, but Wozzeck stops her. The moon is shining bright red. Wozzeck becomes determined that if he can not have Marie, no one else can, and he stabs her.
Scene 3 (Invention on a Rhythm): People are dancing in a pub. Wozzeck enters, and when he sees Margret, he dances with her and pulls her onto his lap. He insults her, and then asks her to sing him a song. She sings, but then notices blood on his hand and elbow; everyone begins to shout at him, and Wozzeck rushes out.
