Development of an Astrophysical Facility for the Studies of Fast Variable Processes

We finalized the development of a facility for observations (including remote observations) of the star-shaped objects with the temporal resolution of 1 micro second. The facility is featuring a multimode panoramic photospectropolarimeter, 1 or 2 coordinate-sensitive quanta detectors and a four-computer measurement control and registration system. Observational modes: photometric in the UBVR colour bands, spectral (50 or 10 nm per pixel), photopolarimetric and spectropolarimetric in 2 or 4 polarisation planes.

RATAN-600 Multi-Octave Frequency Range Overlapping Finalized

We finalized the multi-octave overlapping of the RATAN-600 frequency range from 0.75 to 18GHz with the frequency resolution of 1% using the parallel spectrum analysing complex. In combination with large effective area, the RATAN-600 offers new opportunities of studying the thin structure of the solar corona radio emission. We have implemented the registration of the instantaneous spectra throughout the entire frequency range. Regular observations of the Sun go through an automated reduction and are available at http://www.spbf.sao.ru/prognoz/ within 4 minutes from the acquisition time.
