Proper Motions, Hipparcos Stars

Scientific paper

At the end of 20th century, the HIPPARCOS Catalogue was finished, and near 4.4 million astrometric optical observations (made at 33 observatories) of near 4.5 thousand HIPPARCOS stars used for the investigations of latitude/universal time UT0 variations were collected. Nowadays, these optical observations are useful for improvement of proper motions of HIPPARCOS data; the long history optical observations (during the interval 1899.7-1992.0) can improve them (at the first place, the long term part). Here, some results of improved proper motions in declination (of some HIPPARCOS stars) are presented; we used the optical observations of latitude variations made with Photographic Zenith Tubes (PZT).
