ABSTRACT. Photographic observations of XX century contained numerous and varied information about all objects and events of the Universe fixed on plates. The original and interesting observations of small bodies of the Solar system in previous years can be selected and used for various scientific tasks. Existing databases and online services can help make such selection easily and quickly.The observations of chronologically earlier oppositions, photometric evaluation of brightness for long periods of time allow refining the orbits of asteroids and identifying various non-stationaries.Photographic observations of Northern Sky Survey project and observations of clusters in UBVR bands were used for global search for small bodies of Solar system. Total we founded 2486 positions of asteroids and 13 positions of comets. All positions were compared with ephemeris.It was found that 80 positions of asteroids have a moment of observation preceding their discovery, and 19 of them are chronologically the earliest observations of these asteroids in the world.
Abstract. We describe a key project of the Ukrainian Virtual Observatory (UkrVO), namely, a collaboration to digitize the large collections of photographic plates that had been exposed during more than 100 years at Ukrainian observatories, and to combine the digitized images with CCD archives to form the UkrVO Joint Digital Archive. The application of flatbed scanners for digitizing plates is discussed.Keywords. astronomical data bases: miscellaneous
Plate Collections of Ukrainian ObservatoriesThe archives of photographic observations at three observatories of Ukraine-at Kyiv, Lviv and Odessa Universities-are significant through both their size and their age; the collections are very extensive, and cover the period from the late-19 th century to the mid-20 th century. A small part of the plates from that period may have been dispersed when observing activities were severely disrupted during WWI and WWII and several eastern European observatories lost major parts of their plate collections. The loss of a collection also means the loss of information about the observing methods used.The history of progress in observational techniques has a number of dimensions, cultural as well as scientific. Observing involved Hartmann or hexagonal diaphragms, tubular, wedge or Fesenkov photometers, hypersensitizing in special chemical solutions, and many other methods and processes that have now been relegated to the status of littleknown techniques of historic interest only. Unfortunately, it is difficult to recover complete information about the images that were observed, as logs and other records were often lost. Nevertheless, each series of historic photographic observations is worthy of careful attention and study. We therefore included the preservation of historical observational archives within the framework of the Ukrainian Virtual Observatory project without segregation into scientific and historical sections.
