... 3 ­ Sternberg State Astronomical Institute, Moscow, :jeanna@sai.msu.ru The graphic method of the analysis of an arrangement of linear structural elements on geographical and geological maps of continents (A.V.Dolitsky, [1]) has allowed to find out global stress fields of the past and among them one which directions (the main normal and maximal tangents) describe more than 80 % of all linear elements of a relief. ... The found poles share program way on density of an arrangement on 3-4 groups. ...

It is a matter of common knowledge that in processes of genesis and evolution of many solar phenomena participate magnetic fields of sunspots. ... As a basis for formation of the database we take data on magnetic fields, collected by set of observatories during many years of observations. ... Section "Magnetic field data" contains data of magnetic field observation for separate sunspots, presented in standard text format (ASCII). ... Description of structure of these files is presented here . ...

... A radio galaxy is a galaxy that emits an unusually big amount of energy at radio wavelengths. ... Inside of each galaxy with an active nucleus (radio galaxies are among them) there must be a system of a "central machine" responsible for the colossal amount of the emitted energy from radio to gamma ranges. ... Sometimes a radio source in an active galaxy may flare again if the needed conditions appear (a new portion of matter would fall into the furnace of the "central machine"). ...

... 400mm f/2.8 Nikor lens: images the sky on the entrance slit. ... The optical system maintains image quality along the slit length so that each row of the image is a spectrum of that spatially selected region of the sky. 180mm f/2.8 Nikor lens: collimates the light from the slit. ... The auxiliary optical platform on WISPI now accomodates a short focal lens and a guiding/imaging video system that may use sub-pixel corrections to provide feedback to the tracking drive motors. ...
