Astrographic Catalogue 2000 ( USNO )
The Astrographic Catalogue (AC) was an international effort designed to photograph and measure the positions of all stars brighter than magnitude 11.0. In total, over 4.6 million stars were observed, many as faint as 13th magnitude. This project was started over 100 years ago. The sky was divided among 20 observatories, by declination zones. Each observatory exposed and measured the plates of its zone, subsequently publishing the plate measures.
The U.S. Naval Observatory has completed data entry of the printed volumes of the AC, has completed the data reduction of each zone, and has converted the positions to the system defined by Hipparcos. The resulting catalog, called AC 2000, is now available.

The database holds the descriptions of many catalogs, such as radio sources, X-ray objets, minor planets, etc. It also holds the descriptions of more than 10,000 images, mainly from the ROSAT and Einstein Observatory satellites, and can be enriched with the user own data. The program is ASCOM compliant and can drive a telescope.

Astronomical Ring for Access to Spectroscopy ( ARAS )
ARAS is an informal group of volunteers who aim to promote cooperation between professional and amateur astronomers in the field of spectroscopy. The purpose of ARAS in fostering the participation of amateur astronomers in scientific projects in the field of spectroscopy is not to implement and coordinate observing campaigns. This is the role of astronomy research scientists, laboratories or international consortiums. ARAS will however attempt to consolidate the acquired data into a web database and will ensure that the quality of its data is compatible with scientific processing methods. ARAS was held from 6 to 11 May 2003 by the 8th "Ecole d'Astrophysique d'Oléron, France" and organized by Jean-Pierre Rozelot ("Observatoire de la Côte d'Azur", France), under the aegis of the "Centre National de la Recherche Scientifique" (CNRS). This session essentially focused on the theme "Astrophysics Tools for Cooperation between Amateur and Professional Astronomers", with special emphasis on spectrography. It demonstrated that amateurs can make a useful contribution to observation in a broad range of fields. [also in French, Italian, Portuguese, and Spanish]

Astronomical Software & Documentation Service ( ASDS )
The Astronomical Software and Documentation Service (ASDS) is a network service that allows you to find existing astronomical resources for solving your problem. ASDS started life as the Astronomical Software and Documentation Service, devoted entirely to astronomical software packages and their associated on-line documentation. Much code is rewritten these days, not because anyone has found a fundamentally better way to solve the problem, but because they simply don't know who has already done it, whether the code runs on the system they have available, or where to get it if it does. That is the problem that ASDS was intended to solve. The objectives of ASDS changed in 1998 when its scope was expanded to include astronomical observing sites and their associated telescope and instrument manuals, taken from a listing maintained by Liz Bryson (bryson@cfht.hawaii.edu). The service was renamed at this point.

The Atacama Large Millimeter Array (ALMA) is a millimeter wavelength telescope. The U.S. side of the project is run by the National Radio Astronomy Observatory (NRAO), operated by Associated Universities, Inc., under cooperative agreement with the National Science Foundation (NSF). The European side of the project is a collaboration between the European Southern Observatory (ESO), the Centre National de la Recherche Scientifique, the Max-Planck-Gesellschaft, the Netherlands Foundation for Research in Astronomy and Nederlandse Onderzoekschool Voor Astronomie, and the United Kingdom Particle Physics and Astronomy Research Council.

Atlas of the Universe
Contains 3D maps of the universe zooming out from the nearest stars to the scale of the Milky Way galaxy and onwards to the surrounding superclusters and out to the entire visible universe.
ATNF - Australia Telescope Compact Array ( ATCA, Narrabri )
The Paul Wild Observatory, near Narrabri, is part of the Australia Telescope National Facility (ATNF), and operated by the CSIRO; the Officer-in-Charge is Dr Graham Nelson. The Narrabri site contains the Australia Telescope Compact Array, which consists of five antennas located along a 3-km railtrack, and a 6th antenna 3 km further to the west.
ATNF - Australia Telescope National Facility ( CSIRO )
CSIRO's Australia Telescope National Facility (ATNF) is an organisation that supports and undertakes research in radio astronomy. It operates the Australia Telescope, the collective name for a set of radio telescopes in New South Wales. These telescopes are used, individually or together, to study objects in the Universe ranging from the remains of dead stars to entire galaxies.
ATNF - Mopra Observatory ( ATNF Mopra )
The Mopra 22-m antenna is part of the Australia Telescope National Facility (ATNF), operated by the CSIRO. It is intended for use in conjunction with other AT antennas (the six 22-m dishes at Narrabri, and the 64-m Parkes dish) to form the Long Baseline Array. Like the Parkes antenna, it is also used for single-dish operation; mm-wavelength receivers are to be installed soon.
ATNF - Parkes Observatory ( ATNF Parkes )
The CSIRO Australia Telescope National Facility operates a group of radio telescopes collectively known as the Australia Telescope. The ATNF Parkes Observatory consists of a 64m telescope which is used as an independent instrument, and networked with other Australian and international radio telescopes for VLBI.
ATNF Parkes 21cm Multibeam Survey
The Parkes 64-m telescope is commencing an HI Southern Sky and Zone of Avoidance survey in 1996. The survey will cover redshifts up to 0.04, and be sensitive to objects with HI mass between 10^6 and 10^10 solar masses, depending on distance. This will be the first extensive "blind" survey of the 21cm extragalactic sky.
Atomic Data for Astrophysics
This service provides links to archives of atomic data for astrophysics at the University of Kentucky and other sites accessible through the WWW. The ADfA page is regularly updated.
Atomic Line List
The atomic line list is a compilation of approximately 855,000 allowed, intercombination and forbidden atomic transitions with wavelengths in the range from 0.5 Å to 1000 µm. Its primary intention is to allow the identification of observed atomic absorption or emission features. The list is nearly complete for all ionization stages of all elements up to zinc. Transition probabilities are available for nearly 14% of the lines; they are mostly derived from Opacity Project data.
Auckland Observatory and Stardome Planetarium
Situated in New Zealand's largest city. A public Observatory established in 1967. Now with a new (1997) 11 metre Zeiss planetarium.
Research interests include photometry of binary and variable stars.

Automated Patrol Telescope ( APT )
The Automated Patrol Telescope (APT) is a wide-field CCD imaging telescope, which is operated by the University of New South Wales at Siding Spring Observatory, Australia.
Automated Plate Scanner ( APS, Univ. Minnesota )
The APS Catalog of the POSS I contains millions of entries for stars and galaxies, and the corresponding Image Database contains their pixels and more. The data behind the Object Catalog and Image Database are generated from digitized Palomar Observatory Sky Survey plates. Object Catalog entries include calibrated magnitudes in two colors, positions to 0.2 arcseconds, confidence measures on neural network image classifications, colors, and various other useful parameters.
AVHRR Land Pathfinder Data Set ( AVHRR )
The Pathfinder AVHRR Land data sets are global, multichannel, land surface data derived from the Advanced Very High Resolution Radiometers (AVHRR) on the NOAA/TIROS operational meteorological satellites (NOAA-7, -9, and -11) which provide a continuous daily and composite data set from July 1981 through the present. These data, when complete, will enable studies of global vegetation and surface characteristics over more than a decade. Every effort has been made to provide a consistently processed data record by cross-calibrating instruments and minimizing changes to the processing algorithm during the processing of the 1981 to present data.
