city, Riverside county, southwestern California, U.S. Located about 45 miles (70 km) southeast of Los Angeles, Corona lies at the east end of the Santa Ana Canyon on the northeastern edge of the Santa Ana Mountains. Originally inhabited by Luiseno Indians, it became part of the Rancho La Sierra land grant. It was laid out as South Riverside when Queen Colony, a citrus growers' organization, was established (1886). In 1896 it was renamed Corona (Spanish: "Crown") for a 3-mile (5-km) circular drive that is now around the central city and was the site of international automobile races from 1913 to 1916. Largely known for its agricultural products, it was the site of the first lemon-processing plant (1915) in the United States and subsequently developed as a citrus-processing and shipping centre. Other crops include alfalfa, sugar beets, tomatoes, and walnuts. Light manufacturing, mining, and retail are economically important. A notable local attraction is the Fender Museum of Music and the Arts (opened 2002), which provides educational programming for children. Mathews Dam to the east impounds Lake Mathews. Cleveland National Forest, Chino Hills State Park, and Glen Ivy Hot Springs are nearby. Inc. 1896. Pop. (1990) 76,095; (2000) 124,966.
brightly illuminated area surrounding an atmospheric light source, such as the Sun, when the light is propagated through a medium containing many sizes of particles or droplets that are large compared to the wavelength of the light. Because the wavelength of visible light is about 0.00005 cm (0.5 micrometre), particles of size greater than about 0.0001 cm (1 micrometre) will give rise to aureoles. Physically, aureoles are caused by the diffraction of large amounts of the incident light around the edges of the particles in directions deviating only slightly from that of the light source. In the atmosphere, aureoles may frequently be observed when a thin cloud passes between the Sun or Moon and the observer. If the cloud is composed of a wide range of droplet sizes, then the aureole will be observed. It is generally white in colour, but a brownish outer ring and bluish inner edge may sometimes be observed. Dense atmospheric haze also produces an easily observable solar aureole, apparent as a very bright region immediately surrounding the Sun, with a gradual tapering off of brightness with an increasing angle from the Sun.
