Near-Earth Observations by Spread Telescopes

We suggest the all-sky survey at the International Space Station by four little wide-angle telescopes with polarization filters and CCD-arrays spread by several meters one from another. The video information processing will be carried out by real-time multiprocessor system on the board of the station. This experiment would allow to observe the sunlit space debris and meteoroids of centimetre size with their distances and velocities estimations at the distances up to 20 km from station and to investigate the interplanetary and interstellar medium by the making of polarization sky maps and detecting the weak-contrast features on it.

Multi-Color Polarimetry of the Twilight Sky. The Role of Multiple Scattering as the Function of Wavelength

This work is devoted to the study of solar light that experiences single and multiple scattering in the atmosphere at the twilight time. The work is based on polarimetric observations of the twilight sky that were conducted in 1997 and 2000 for different color bands. Basing on the results of observations, the contribution of single-scattered light depending on the wavelength for the light stage of twilight is obtained. The correlation of color and polarization properties of the twilight sky is investigated with an account of multiple scattering

The search for possible mesolensing of cosmic gamma-ray bursts. Double and triple bursts in BATSE catalogue

The work is devoted to the search for possible effect of gravitational lensing on the objects like globular stellar clusters (mesolensing) on the lightcurves and spectra of large number of gamma-ray bursts from BATSE catalogue. The general properties and different types of such event were considered. As the result 11 possibly mesolensed gamma-ray bursts were found. The properties of possible mesolensed are investigated.
