... During all period of our investigations Dr. N.Sumzina from the Institute of Applied Astronomy of RAS had prepared the Numbered Minor Planet positions from MPC Database for our processing with kind permission of the Director of Minor Planet Center Prof. Braian Marsden. ... Our extensive processing of the MPC data allows us to conclude that CCD observations of the Numbered and Unnumbered Minor Planets have the errors, sometimes very crude. ...

... The reduction system of observations FADPS (description in Russian) (Flexible Astronomical Data Processing System) for data of wide-band receivers of the first observation cabin of the radio telescope RATAN-600 had been created under the Unix-like operational system DEMOS for computers of the SM-1420-type (PDP/11) in 1987 for observation analysis and estimates of coordinates and flux densities of radio sources. ... FADPS: flexible astronomical data processing system at RATAN-600 in UNIX environment....

ATMoB "Open Cluster Observing Award " Guidelines Purpose: To promote observing among the membership of the Amateur Telescope Makers of Boston through participation in the Open Clusters Observing Awards program. Introduction: This awards program is oriented towards visually observing open clusters above magnitude 9.9. ... It turns out that a very unprejudiced and convenient method to dermine the limiting magnitude is to count the number of visible stars in certain areas on the sky. ...

NMW survey overview . Access image archive . ... The New Milky Way survey aims to detect bright (V<13.5) optical transients near the Galactic plane using an automated wide-field (8x6 deg.) system capable of surveying the whole Milky Way area visible from the observing site in one night. ... All images obtained during the transient search survey are available online (please use the image archive access form ). ... Images per field: . ... Images per night: . ...

... We have presented the chirplet transform, which may be viewed as a generalization of both the short-time Fourier transform (STFT) and the wavelet transform (WT). ... The Gaussian chirplet transform (GCT) results in a complex function of four variables: time, frequency, scale, and ``chirprate''. ... The full continuous chirplet transform (CCT) that can be obtained using only a single mother chirplet results in a complex function of five variables: time, frequency, scale, chirprate, and dispersionrate...

... It is proved that semi-casimirs induce well-defined operators on conformal blocks and there is a natural projection of $T_\Sigma {\Cal M}_{g,2}^{(1)}$ onto the space of these operators where ${\Cal M}_{g,2}^{(1)}$ is the moduli space of Riemann surfaces with two marked points and fixed 1-jets of local coordinates at those points, $\Sigma\in {\Cal M}_{g,2}^{(1)}$ is the Riemann surface involved into the definition of Krichever-Novikov algebras in question. ...
