Orange County Astronomers
The Orange County Astronomers (OCA) is a 501(c)(3) non-profit, civilian-led astronomy organization in Orange County, southern California. It was formed in 1967 and currently operates with around 800 concurrent members; they offer beginner courses in astronomy, and have meetings on the second Friday of every month at Chapman University. Currently, the OCA offers a dark-sky site to viewers, which includes a 22-inch Schmidt-Cassegrain telescope and public-use observation areas. In addition, the OCA has been registered as an affiliate of the Astronomers Without Borders program since March of 2012. OCA Observatory In September of 1984, a 22-inch Schmidt-Cassegrain telescope along with an observatory were opened in the namesake of William Kuhn. This telescope is operated at the OCA Observatory, located at a dark-sky site that is a two hour drive from Orange County.

Nonprofit Organization
A nonprofit organization (NPO) or non-profit organisation, also known as a non-business entity, not-for-profit organization, or nonprofit institution, is a legal entity organized and operated for a collective, public or social benefit, in contrast with an entity that operates as a business aiming to generate a Profit (accounting), profit for its owners. A nonprofit is subject to the non-distribution constraint: any revenues that exceed expenses must be committed to the organization's purpose, not taken by private parties. An array of organizations are nonprofit, including some political organizations, schools, business associations, churches, social clubs, and consumer cooperatives. Nonprofit entities may seek approval from governments to be Tax exemption, tax-exempt, and some may also qualify to receive tax-deductible contributions, but an entity may incorporate as a nonprofit entity without securing tax-exempt status.

Mobile Home
A mobile home (also known as a house trailer, park home, trailer, or trailer home) is a prefabricated structure, built in a factory on a permanently attached chassis before being transported to site (either by being towed or on a trailer). Used as permanent homes, or for holiday or temporary accommodation, they are often left permanently or semi-permanently in one place, but can be moved, and may be required to move from time to time for legal reasons. Mobile homes share the same historic origins as travel trailers, but today the two are very different, with travel trailers being used primarily as temporary or vacation homes. Behind the cosmetic work fitted at installation to hide the base, mobile homes have strong trailer frames, axles, wheels, and tow-hitches. History In the United States, this form of housing goes back to the early years of cars and motorized highway travel. It was derived from the travel trailer (often referred to during the early years as "house traile ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Minor Planet Circulars
The Minor Planet Center (MPC) is the official body for observing and reporting on minor planets under the auspices of the International Astronomical Union (IAU). Founded in 1947, it operates at the Smithsonian Astrophysical Observatory. Function The Minor Planet Center is the official worldwide organization in charge of collecting observational data for minor planets (such as asteroids), calculating their orbits and publishing this information via the '' Minor Planet Circulars''. Under the auspices of the International Astronomical Union (IAU), it operates at the Smithsonian Astrophysical Observatory, which is part of the Center for Astrophysics along with the Harvard College Observatory. The MPC runs a number of free online services for observers to assist them in observing minor planets and comets. The complete catalogue of minor planet orbits (sometimes referred to as the "Minor Planet Catalogue") may also be freely downloaded. In addition to astrometric data, the MPC collect ...
