... Advises . Contact Advises . As an advise for amateurs we would like to underline: if it's possible, try to observe 3 asteroid positions per night and do not neglect to observe the Numbered Minor Planets in your telescope field of view as a "by product" of your observational programs. ... We think such estimations ought to be produced every morning after CCD observations of the moving celestial objects by observer himself. ...

Observer's software to handle spectrographic observations will be written by JHU and installed on the Fermilab supplied observatory workstation. ... UW will be responsible for the slithead latch-down control. ... Database computer at APO: The observer's software will query the observatory database for information on the currently installed fiber cartridge. ...

Pulkovo NEO Page . ... NEA Accuracy Estimation . ... The estimation of accuracy of the current CCD observations of asteroids and comets is constantly performed at Pulkovo Observatory. ... The (O-C) values, so called "Observed" minus "Calculated" positions, characterize numerically the observations of any observatory, both professional and amateur, during a short period (one or several close nights). ... So the (O-C) values for these objects nearly entirely define the errors of observations. ...

The information path to prepare, perform and reduce a radioastronomical observation, using the Arcos correlator , is schematized in the figure: . The programs reside part on the computer network of the Arcetri Observatory, and part at the Medicina Radio Telescope . All programs running at Arcetri are written for a Sun workstation, and are public domain software, available upon request. Programs running at the telescope are written for a PC with DOS/Windows (or Linux).
