Oberon (moon) the spacecraft "Voyager 2" took several images of Oberon in January 1986, allowing 40% of the moon's surface to be mapped. Oberon was discovered by William Herschel on January 11, 1787; on the same day he discovered Uranus's largest moon, Titania. He later reported the discoveries of four more satellites, although they were subsequently revealed as spurious. For nearly fifty years following their discovery, Titania and Oberon would not be observed by any instrument other than William Herschel's, although the moon can be seen from Earth with a present-day high-end amateur telescope. All of the moons of Uranus are named
Oberon (operating system) together with the editor called Write yielded V2. As foreshadowed in the table in section history above there was a major fork in the beginning of 1990s: V4 vs. System 3: The group around Jürg Gutknecht introduced persistent objects and object-libraries thereby extending the kernel. The group around realized similar features by introducing active elements mapped to a special character thereby extending fonts without changing the kernel. System 3 was sometimes also called Spirit of Oberon and later renamed to ETH Oberon, whereas V4 was sometimes also called Linz Oberon. A version of the Oberon System 3, which was integrated
