The Second Us Naval Observatory Ccd Astrograph Catalog (ucac2)
The second USNO CCD Astrograph Catalog, UCAC2 was released in July 2003. Positions and proper motions for 48,330,571 sources (mostly stars) are available on 3 CDs, supplemented with 2MASS photometry for 99.5% of the sources. The catalog covers the sky area from −90 to +40 degrees declination, going up to +52 in some areas; this completely supersedes the UCAC1 released in 2001. Current epoch pos...
متن کاملUs Naval Observatory Ephemerides of the Largest Asteroids
A new set of ephemerides for 15 of the largest asteroids has been produced for use in the Astronomical Almanac. The ephemerides cover the period from 1800 through 2100. The internal uncertainty in the mean longitude at epoch, 1997 December 18, ranges from for 7 Iris through for 65 Cybele, and 0A.05 0A.22 the uncertainty in the mean motion varies from per century for 4 Vesta to per century for 5...
متن کاملCool dwarfs stars from the Torino Observatory Parallax Program
Aims. We investigate and parameterize high proper motion red stars in the Torino Observatory Parallax Program. Methods. Observations of 27 objects were made over the period 1994–2001 on the 1.05 m Torino telescope. The trigonometric parallaxes and proper motions were determined using standard techniques. Results. We determine parallaxes and proper motions, and by comparison to models we infer m...
متن کاملThe Smithsonian Astrophysical Observatory Solar Constant Program
The Astrophysical Observatory of the Smithsonian Institution (APO) made measurements of the solar constant at many locations on the earth's surface from 1902 to 1962. These measurements have been interpreted by various authors to show that the sun has both a long-term secular change in brightness and cyclic variations. The same data set has been used by other authors to show that the sun is con...
