The photomosaic from NASA's "Wave at Saturn" campaign. The collage includes some 1,600 photos taken by members of the public on The Day the Earth Smiled.
The 1990 storm was an example of a Great White Spot, a short-lived phenomenon that occurs once every Saturnian year, roughly every 30 Earth years, around the time of the northern hemisphere's summer solstice. [63] Previous Great White Spots were observed in 1876, 1903, 1933, and 1960, with the 1933 storm being the best observed. [64]
Hyperion is redder than Phoebe and closely matches the color of the dark material on Iapetus. Hyperion has a porosity of about 0.46. [9] Although Hyperion is the eighth-largest moon of Saturn, it is only the ninth-most massive. Phoebe has a smaller radius, but it is more massive than Hyperion and thus denser. [7]
The phenomenon is somewhat periodic at 28.5-year intervals, when Saturn's northern hemisphere tilts most toward the sun. Usually this is during the solar longitude of around 90-180°, only the 2010 GWS was ahead of its time shortly after equinox. The following is a list of recorded sightings. Six events are recognized as Great White Spots. [5
Tethys (/ ˈ t iː θ ɪ s, ˈ t ɛ θ ɪ s /), or Saturn III, is the fifth-largest moon of Saturn, measuring about 1,060 km (660 mi) across.It was discovered by Giovanni Domenico Cassini in 1684, and is named after the titan Tethys of Greek mythology.
Giovanni Domenico Cassini, discoverer of Iapetus. Iapetus was discovered by Giovanni Domenico Cassini, an Italian-born French astronomer, in October 1671.This is the first moon that Cassini discovered; the second moon of Saturn to be discovered after Christaan Huygens spotted Titan 16 years prior in 1655; and the sixth extraterrestrial moon to be discovered in human history.

It is Saturn's ninth-largest moon, but it is the eighth-most massive. Hyperion, another one of Saturn's moons, has a larger radius, but is less massive than Phoebe. Phoebe rotates every nine hours and 16 minutes, and completes a full orbit around Saturn in about 18 months. Its surface temperature is on average 75 K (−198.2 °C).
